How To Find Factors of 32 Through Division Method?

To determine the factors of 32, we are using the division method. This approach requires you to multiply a sequence of natural integers by 32. The numbers that divide the 32 completely without leaving any remainder are known as factors of 32. The following are the detailed steps for finding the factors of 32 using the division method:

• 32 ÷ 1 = 32
• 32 ÷ 2 = 16
• 32 ÷ 4 = 8
• 32 ÷ 8 = 4
• 32 ÷ 16 = 2
• 32 ÷ 32 = 1
• 64 ÷ 2= 32

Therefore, we can see that 1, 2, 4, 8, 16, and 32 are the numbers that do not leave any remainder when divided by 32. Hence, the factors of 32 are 1, 2, 4, 8, 16, and 32. 64 is also a factor of 32, though it cannot divide by 32. But 32 can divide it by 2.

What Is the Prime Factorization of 32?

Check if the given number is a prime number. If the given number is a prime number then there will be only two factors i.e 1 and the number itself. If the given number is a composite number, then it will have more than two factors.
Since 32 has more than two factors, it’s a composite number. Hence, we can use the prime factorization method to find the factors of 32.

The steps to find prime factors of 32 using the prime factorization method are given below:

Step 1: Divide the number 32 by the smallest prime number that is divisible by 32. Hence the smallest prime number that is divisible by 32 is 2. So, 32 ÷ 2 = 16

Step 2: Now, divide the number 16 (quotient) by the smallest prime number which is 2. So, 16 ÷ 2 = 8

Step 3: Divide the quotient by 2 repeatedly until you get the number prime number as the quotient. 8 ÷ 2 = 4, 4 ÷ 2 = 2

Step 4: Now we got 2 as the quotient. Dividing 2 with 2 gives us 1. So, 2 ÷ 2 = 1 The quotient is 1. Since 1 cannot be divided further, the prime factors of 32 are 2 X 2 X 2 X 2 X 2 or 2⁵.

What Is the Factor Tree of 32?

Students can also use the factor tree to find the prime factors of 32. In this method, we will place the number 32 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 (32). 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 32.

Step 1: Let’s place the number 32 at the top of the factor tree and write down 32 in pairs, that is, 2 and 16.

Step 2: Since 2 is a prime number, we can no longer separate it. Let us circle 2 and move on to the next number. We will now divide 16 into 2 and 8.

Step 3: As we can see, 2 is a prime number but 8 is not, so we will split 8 into 2 and 4.

Step 4: Now again, we will leave 2 as it is because it is a prime number, but we will break 4 into 2 and 2.

Step 5: We can see that 2 is a prime number. The branches in the factor tree will now be all the prime numbers. Hence, circling all the branches, 2⁵ or 2 X 2 X 2 X 2 X 2= 32, which are 32 prime factors.

There are many ways in which we can write the factor tree of 32. Below is an image representation of the factor tree of 32, choosing 4 and 8 as pair factors of 32.
