Given Input Data is 315, 215, 920, 863

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

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 215 is 5 x 43

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 863 is 863

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(315, 215) = 13545

GCD(315, 215) = ( 315 x 215 ) / 13545

GCD(315, 215) = 67725 / 13545

GCD(315, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 920

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

LCM(5, 920) = 920

GCD(5, 920) = ( 5 x 920 ) / 920

GCD(5, 920) = 4600 / 920

GCD(5, 920) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 863

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

LCM(5, 863) = 4315

GCD(5, 863) = ( 5 x 863 ) / 4315

GCD(5, 863) = 4315 / 4315

GCD(5, 863) = 1

GCD of 315, 215, 920, 863 is 1
