Given Input Data is 637, 763, 520

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

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 763 is 7 x 109

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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(637, 763) = 69433

GCD(637, 763) = ( 637 x 763 ) / 69433

GCD(637, 763) = 486031 / 69433

GCD(637, 763) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 520

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

LCM(7, 520) = 3640

GCD(7, 520) = ( 7 x 520 ) / 3640

GCD(7, 520) = 3640 / 3640

GCD(7, 520) = 1

GCD of 637, 763, 520 is 1
