Therefore, GCD of numbers 936, 640, 387, 980 is 1

Given Input Data is 936, 640, 387, 980

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

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 387 is 3 x 3 x 43

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

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(936, 640) = 74880

GCD(936, 640) = ( 936 x 640 ) / 74880

GCD(936, 640) = 599040 / 74880

GCD(936, 640) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 387

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

LCM(8, 387) = 3096

GCD(8, 387) = ( 8 x 387 ) / 3096

GCD(8, 387) = 3096 / 3096

GCD(8, 387) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 980

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

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

GCD(1, 980) = 980 / 980

GCD(1, 980) = 1

GCD of 936, 640, 387, 980 is 1
