Finding factors of 36 using the Prime Factorization method

The prime factorization method is the most common method to represent 36 or any other number. Its other form, the prime factor tree method, is a visual method to represent factors of 36. It helps in determining prime factors of 36. A factor tree is not unique for a given number. Instead of expressing 36 as 2 × 18, we can express 36 as 6 × 6.

We need to divide 36 from the smallest number to the biggest number as shown-

• With the help of divisibility rules, we need to find out the smallest factor of the given number. Here, we have 36, which is an even number. It is divisible by 2. In other words, 2 divides 36 with no remainder. Therefore, 2 is the smallest prime factor of 36.
• 36 ÷ 2 = 18. We need to repeat the steps with other numbers until we get the remainder of 0.
• 18 ÷ 2 = 9. Here, 9 is the quotient. Now, we need to divide it by other numbers and find the prime factors of the 9.
• 9 ÷ 3 = 3. Here 3 is the prime number. We can execute another step to divide 3 by 3. We will get remainder 1. After that, our process is completed, and we get a factor of 36.

Prime factorization of 36 using the prime factorization method is 2 × 2 × 3 × 3 = 2² × 3².
