Steps to find Prime Factors of 156 by Division Method

To find the primefactors of 156 using the division method, follow these steps:

  • Step 1. Start dividing 156 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
  • Step 2. After finding the smallest prime factor of the number 156, which is 2. Divide 156 by 2 to obtain the quotient (78).
    156 ÷ 2 = 78
  • Step 3. Repeat step 1 with the obtained quotient (78).
    78 ÷ 2 = 39
    39 ÷ 3 = 13
    13 ÷ 13 = 1

So, the prime factorization of 156 is, 156 = 2 x 2 x 3 x 13.

Steps to find Prime Factors of 156 by Factor Tree Method

We can follow the same procedure using the factor tree of 156 as shown below:

So, the prime factorization of 156 is, 156 = 2 x 2 x 3 x 13.

Introduction to Prime Factors?

In mathematics, prime numbers are defined as all those natural numbers greater than 1 that has only two divisors one being number 1 and the other being the number itself. When we express any number as the products of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 156 are 2 x 2 x 3 x 13.

Properties of Prime Factors

  • For any given number there is one and only one set of unique prime factors.
  • Any number can have only 1 even prime factor and that is number 2.
  • Two prime factors are always coprime to each other.
  • 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 156 but not a prime factor of 156.
