Answer 1

Answer:

hello friend

The HCF of 20,28,36can also be found by prime factorisation of these numbers as follows:

20=2×2×5

28=2×2×7

36=2×2×3×3

The common factor of 20,28,36 is 2×2=4

If the highest common factor (HCF) of two numbers is equal to 1, then they are called co-prime or relatively prime. HCF of co-prime numbers 4 and 15 was found as follows of factorisation 4=2×2 and 15=3×5, since there is no common prime factor,so HCF of 4 and 15 is 1.

hope it helps you I know it is very difficult to you because it's too long.

good luck
