How To Find Factors of 33 Using the Division Method?

To determine the factors of 33, we are using the division method. This approach requires you to multiply a sequence of natural numbers by 33. The numbers that divide 33 completely without leaving any remainder are known as 33 factors. The following are the detailed steps for finding factors of 33 using the division method:
33 ÷ 1 = 33
33 ÷ 3 = 11
33 ÷ 11 = 3
33 ÷ 33 = 1

Therefore, we can see that 1, 3, 11, and 33 are the numbers that do not leave any remainder when divided by 33. Hence, the factors of 33 are 1, 3, 11, and 33.

What Is the Prime Factorization of 33?

Check if the given number is a prime number. If the given number is a prime number, then it has only two factors: 1 and 33. If the given number is a composite number, then it has more than two factors.
Since 33 is the composite number, we have more than two factors. Hence, we can use the prime factorization method to find the factors of 33.

The steps to find prime factors of 33 using the prime factorization method are given below:

Step 1: Divide the number 33 by the smallest prime number that is divisible by 33. Hence, the smallest prime number that is divisible by 33 is 3.
So, 33 ÷ 3 = 11

Step 2: Now, divide the number 11 (quotient) next. But since 11 is a prime number by itself, it can be divided only by 1 and 11.
So, 11 ÷ 11 = 1
The quotient is 1. Since 1 cannot be divided further, the prime factors of 33 are 3 X 11. We can also write it down as 3 and 11, as both of them are prime numbers.

What is the Factor Tree of 33?

Students can also use the factor tree to find the prime factors of 33. In this method, we will place the number 33 at the top of the factor tree. Now, as part of the branches, we will write down any set of pair factors of the given number (33). Now, again, we will split the pair of factors into factors. This process will be continued until the branches become prime numbers. Now, circling all the prime numbers will give us the prime factors of 33

There are many ways in which we can write the factor tree of 33. Below is an image representation of the factor tree of 33, choosing 3 and 11 as pair factors of 33.
