Therefore, GCD of numbers 638, 451, 76, 922 is 1

Given Input Data is 638, 451, 76, 922

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

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 451 is 11 x 41

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 922 is 2 x 461

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(638, 451) = 26158

GCD(638, 451) = ( 638 x 451 ) / 26158

GCD(638, 451) = 287738 / 26158

GCD(638, 451) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 76

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

LCM(11, 76) = 836

GCD(11, 76) = ( 11 x 76 ) / 836

GCD(11, 76) = 836 / 836

GCD(11, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 922

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

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

GCD(1, 922) = 922 / 922

GCD(1, 922) = 1

GCD of 638, 451, 76, 922 is 1
