Given numbers are 638, 724, 635, 979

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 724 are 2 x 2 x 181

Prime factors of 635 are 5 x 127

Prime factors of 979 are 11 x 89

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 638, 724, 635, 979

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(638, 724) = 230956

GCD(638, 724) = ( 638 x 724 ) / 230956

= 638 / 724

= 638

Step2:

LCM(2, 635) = 1270

GCD(2, 635) = ( 2 x 635 ) / 1270

= 2 / 635

= 2

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 638, 724, 635, 979 is 1
