Given numbers are 638, 715, 556, 975

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 715 are 5 x 11 x 13

Prime factors of 556 are 2 x 2 x 139

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 638, 715, 556, 975

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

Apply this formula for all numbers.

Step1:

LCM(638, 715) = 41470

GCD(638, 715) = ( 638 x 715 ) / 41470

= 638 / 715

= 638

Step2:

LCM(11, 556) = 6116

GCD(11, 556) = ( 11 x 556 ) / 6116

= 11 / 556

= 11

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 638, 715, 556, 975 is 1
