When a number is expressed as the product of its prime factors, it is called prime factorization.

For example, 15 = 3 × 5. So, 3 and 5 are prime factors of 15.

HCF of two or more numbers can be obtained by prime factorization. To find the HCF by prime factorization, we first find all the prime factors of the given numbers and then find the product of all the common prime factors. The product is the HCF of the given numbers.

For example:

1. Find prime factorisation of 36.

Prime Factorisation

Prime factorisation of 36 = 2 × 2 × 3 × 3.

= 2² × 3².

[Here two ways to solve factorisation one is tree factorisation method and the other one is by dividing.]

2. Find prime factorisation of 32.

Solution:

Tree Factorisation Method

Prime factorisation of 32 = 2 × 2 × 2 × 2 × 2.

= 2⁵.

3. Find the HCF of 108 and 132 by prime factorization method.

Solution:

HCF of 108 and 132

21Save

108 = 2 × 2 × 3 × 3 × 3

132 = 2 × 2 × 3 × 11

Thus, the HCF is 2 × 2 × 3 = 12
