Therefore, GCD of numbers 115, 936, 640, 863 is 1

Given Input Data is 115, 936, 640, 863

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

Prime Factorization of 115 is 5 x 23

Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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(115, 936) = 107640

GCD(115, 936) = ( 115 x 936 ) / 107640

GCD(115, 936) = 107640 / 107640

GCD(115, 936) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 115, 936, 640, 863 is 1
