Don’t you know what the factors of 168 are? Factors are numbers multiplied together to create a bigger number. To find out all the factors for 168, we need two tools: Dividing and Prime Factorization! Let’s use both of them on our journey through math!! 

Dividing is when we divide one big number: 168 by another smaller whole integer between 1 and 16. Consider dividing it with 2, 3 or 4…If any result comes out with no number left behind  then they become one of the factors – these integers will multiply together fitting  perfectly into our original number. The results obtained using this method were 1,2 ,3 ,4 , 6, 7 8 12 14 21 24 28 42 56 84 & 168 .Such an impressive result it appears.  Now about prime factorisation; It helps in finding detailed information behind each answer mentioned above- Every single result from the divisible test was made up from only two components : A multiple form of 2s’and of 7s’. As long as the combined efforts of primes is there it brings  Numerical perfection (i.e) perfect combination.

Factors of 168 using Multiplication Method

Draft 1

To find the factors of 168, we use a multiplication method called dividing without any remainders (i.e)  that if you divide 168 by an integer between 1 and 168, it will divide with no remainder. Then when each factor of 169 is multiplied together it should result in the original number (168) , say,  1 x 2 x 3 x 4  = 24; 24x 7=168… Another such example is – 8 × 12 × 14 = 2016 which also equals our starting point – 168 – proving these three numbers can go into 168 evenly. Other  possible combinations are 1,2,3 ,4, 6,7,8,12,14, 21,24, 28, 42, 56, 84 or even all sixteen combined at once : 1×2×3×4…. So these sixteen are the ‘factors of 168.

Prime factorization is breaking down a bigger number  into smaller numbers that multiply together to give you the original number. Consider 168, its prime factors are 2x2x2 (aka “to the power of 3”) multiplied by 7. This means that even if the individual pieces of the broken number can be put back together in different ways leading to the original starting point! 

Factor tree of 168


One fun way to break down any number into its prime factors is  factor trees! consider 168. Imagine two branches coming off of this top section where we wrote 168. On each of these branches, write what happens when you divide by 2 twice in a row; so on one branch will be 84 and then 42 on the other branch from that same starting point at 168. Then imagine another pair of branches for each new quotient written in step 3 (84) & 4 (42), both separated again by dividing them all by 2 as before- leaving us with 21 and 1 respectively .Now if you look: You will have 7 little sections branching out like tree limbs . The numbers left are the prime factors; In this case they’re 2 x2x2x3x7 = 168

Factor Pairs of 168

Calculate Pair Factors of

1 x 168=168

2 x 84=168

3 x 56=168

4 x 42=168

6 x 28=168

7 x 24=168

8 x 21=168

12 x 14=168

14 x 12=168

21 x 8=168

24 x 7=168

28 x 6=168

42 x 4=168

56 x 3=168

84 x 2=168

So Pair Factors of 168 are

















Take the number 168. You’ll need to find all the numbers that can divide it without any remainders called “divisors”. Factor pairs is one of the best ways to do this! This is basically finding two factors which when multiplied together equal our original number – in this case, 168. For example: 1 times 168 would be one pair; 2 and 84 makes another pair; 6 x 28 =168 too. Factor-finding isn’t just limited to multiplying either – other methods  such as division or prime factorization can help us discover more combinations.

Fun Facts of Factors of 168

168 is special why?  Because, this number can do lots of amazing stuffs! If we add together all the cubes from 1 to 4 we get 168. That’s just for starters – there are plenty more interesting facts on the way about this great numeral.

Did you know that out of all whole numbers less than itself, 168 has the most number of divisors? (24) scientists call it a ‘highly composite’ number and amazingly enough when written in base-10 form like our normal counting system ,168 also happens to be Harshad Number meaning all its digits divide into exactly 14 parts!!

Last but not least; due to a high number of factors compared with smaller integers and as their sum equals twice its original value ;we say even today after thousands upon thousands years  ,that big old wealthy numeric Duke named “One Hundred Sixty Eight” — HARMONIOUS DIVISOR NUMBER !
