Therefore, GCD of numbers 312, 928, 63, 981 is 1

Given Input Data is 312, 928, 63, 981

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

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 928 is 2 x 2 x 2 x 2 x 2 x 29

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 981 is 3 x 3 x 109

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(312, 928) = 36192

GCD(312, 928) = ( 312 x 928 ) / 36192

GCD(312, 928) = 289536 / 36192

GCD(312, 928) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 63

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

LCM(8, 63) = 504

GCD(8, 63) = ( 8 x 63 ) / 504

GCD(8, 63) = 504 / 504

GCD(8, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 312, 928, 63, 981 is 1
