Given numbers are 634, 687, 126, 721

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 687 are 3 x 229

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 721 are 7 x 103

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

Given numbers are 634, 687, 126, 721

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

Apply this formula for all numbers.

Step1:

LCM(634, 687) = 435558

GCD(634, 687) = ( 634 x 687 ) / 435558

= 634 / 687

= 634

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 634, 687, 126, 721 is 1
