1. Step-by-step explanation:

   We will discuss here about the method of h.c.f. (highest common factor).

   The highest common factor or HCF of two or more numbers is the greatest number which divides exactly the given numbers.

   Let us consider two numbers 16 and 24.

   Factor of 16 are → 1, 2, 4, 8, 16

   Factor of 24 are → 1, 2, 3, 4, 6, 8, 12, 16

   1 × 16, 2 × 8, 4 × 4

   1 × 24, 2 × 12, 3 × 8, 4 × 6

   We see that the highest common factor of 16 and 24 is 8. In short, the Highest Common Factor is expressed as H.C.F.

   Finding H.C.F.

   There are three methods of finding H.C.F. of two or more numbers.

   1. Factorization Method

   2. Prime Factorization Method

   3. Division Method

   1. H.C.F. by factorization method

   Let us consider some examples.

   I. Find the H.C.F. of 36 and 45.

   Factor of 36 are →

   1, 2, 3, 4, 6, 9, 12, 18, 36

   Factor of 45 are →

   1, 3, 5, 9, 15, 45

   1 × 36, 2 × 18, 3 × 12, 4 × 9, 6 × 6

   1 × 45, 3 × 15, 5 × 9

   The common factors of 36 and 45 are 1, 3, 9.

   The highest common factor is 9.
