Therefore, GCD of numbers 656, 220, 79, 895 is 1

Given Input Data is 656, 220, 79, 895

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 79 is 79

Prime Factorization of 895 is 5 x 179

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(656, 220) = 36080

GCD(656, 220) = ( 656 x 220 ) / 36080

GCD(656, 220) = 144320 / 36080

GCD(656, 220) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 79

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(4, 79) = 316

GCD(4, 79) = ( 4 x 79 ) / 316

GCD(4, 79) = 316 / 316

GCD(4, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 895

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

GCD(1, 895) = 895 / 895

GCD(1, 895) = 1

GCD of 656, 220, 79, 895 is 1
