What are the factors of 162
Do you know what special numbers can help us find out all the factors of a larger number? These special numbers are called “factors”. For example, do you remember when we had to break up 162 into little pieces and multiply them together so that it became equal to 162 again? All those pieces were the Factors of 162. Let’s look at an example! The Factors 1, 2, 3 , 6, 9,18, 27 54 81 &162 are divided evenly into our original number – they fit perfectly like puzzle pieces without leaving any extra over. That way if use two or more of these factors then using multiplication will result in getting back our starting point (in this case) which is also known as ‘the product.’
How to Find Factors of 162
The major methods through which we can find the factors of 162 are as follows:
- Factor of 162 using Multiplication Method
- Factors of 162 using Division Method
- Prime Factorization of 162
- Factor tree of 162
Factors of 162 using Multiplication Method
Let’s pretend the number 162 is like a box that we want to open. The only way to do this is by finding two numbers that when multiplied together, equal 162—just like if you wanted to unlock a safe, you would need two keys that work together! To find these special ‘keys’, called factors of the number 162 in Math talk, we can use something called the multiplication method – basically, it means covering all our bases and trying different things until they fit perfectly! After testing out various combinations (in other words, multiplying them!), we found 5 pairs of “keys” or factors:
(1 x162), (2×81), (3×54), (6×27), and finally 9 x 18–once combined produce exactly what was inside the box…aka an answer of one hundred sixty-two!.
Factors of 162 Using Division Method
Have you ever wondered how to find all the factors of a number? Finding these can be tricky but there is a simple method. It’s called the division method!
Think about it this way – let’s say we have an apple that needs to be shared amongst three people, so each person gets one-third or one-third of an apple. The same process happens with numbers too! We divide them by certain other values and check if they give us whole pieces (no remainder). If yes, then those divisors are considered as factors because when multiplied together get us our original value, just like when sharing apples between 3 people: 1/3 + 1/3 +1 / 3 = Our Original Apple. So going back to the factorization approach; we try dividing our number sequentially starting from 1 until its square root which will tell us if any part of it was cleanly divided without leaving remainders in portions such as 2 thirds instead of being able to equalize into something simpler like 6 sixths for example where both sides split evenly(Remainder Zero).

Prime factorization is a way to break down numbers into the building blocks they are made up of. To find out what makes 162, we start by dividing it by smaller prime numbers (2, 3, 5, and 7). If we can’t divide evenly without having some leftovers then that number isn’t part of the answer – so when divided 2 doesn’t work; nor does 3 or 9. But finally when you get to 27 ÷3 =9 and lastly 9÷3=3 – which IS a prime number! That’s our first piece for making 162: two times three raised to four power (2×34), meaning that ultimately if all those pieces were put together in order – 2 x 3 x 3 x 3×3- you’d end up with your original whole:162.
Factor tree of 162
It can be confusing when trying to figure out how many of which prime number makes up a big one. A factor tree is a perfect tool for this! It’s like a diagram with branches that help you track down what numbers make up any given number, all the way down until it’s just primes left – and even then if they’re squared or cubed too. Let’s look at an example: 162 has 2 x 81 =162 as its first branch – so we know our final answer will have two twos in there somewhere – but why? If your question is ‘What are all the prime factors inside this bigger number?’ You’ll need to keep breaking it apart along those branches until you reach small enough pieces only made from single-digit primes (3, 5 7, etc). In this case, after starting with two times eighty-one…we get 3×27=81; 3×9=27; and finally three threes equals nine…2*2*3*3 = 36 Voila — Two twos and two threes now add together equal twenty-four!
Factor Pairs of 162
Calculate Pair Factors of
1 x 162=162
2 x 81=162
3 x 54=162
6 x 27=162
9 x 18=162
18 x 9=162
27 x 6=162
54 x 3=162
81 x 2=162
So Pair Factors of 162 are
(1,162)
(2,81)
(3,54)
(6,27)
(9,18)
(18,9)
(27,6)
(54,3)
(81,2)
When you have a number, such as 162, there are numbers that can be multiplied together to get the original number. For example: if you multiply 1 and 162 together it equals 162; 2 times 81 is also equal 162; 3 times 54 is also equal to 152 (and so on). These pairs of whole numbers which when combined give us our original number called “factor pairs”. In this case, our factor sets for 162 include (1,162 ),(2,81), (3,54 ), etc… When we find factors like these they come in two parts – one part being reflected exactly opposite from the other side – making them mirror images reflecting each other! So remember that every single pair has an inverse or reflection – just like how your face looks the same while looking into a mirrored glass with a reversed view.

Fun Facts of Factors of 162
- It’s part of many different Mathematical patterns. For example, the factors of 162 are 1, 2, 3, 6, 9, 18, and so on until we get to 81 and finally arrive at 16!
- You can also find it in triangular numbers which have three sides like a triangle shape – when you add together the squares of these first three triangles (1 + 3^2 + 6^2), they all equal up to be exactly 162.
- Another thing about this amazing number is that it’s called a ‘Harshad Number’ because if you split up each digit and then add them back together again their sum must divide into 162 without any remainder i(e 1+6+2=9).
- And last but certainly not least – did I tell you already how cool Fibonacci Numbers are? Well, when you put two Fibonacci cubes side-by-side with one another: (1 ^3 plus 2 ^3) what do you think would happen!? That’s right; both those cubes added together = glorious beautiful magical wonderful lovely spectacular KABOOM!!! Aka ……162!
