Given numbers are 687, 638, 651, 372

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 638 are 2 x 11 x 29

Prime factors of 651 are 3 x 7 x 31

Prime factors of 372 are 2 x 2 x 3 x 31

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

Given numbers are 687, 638, 651, 372

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

Apply this formula for all numbers.

Step1:

LCM(687, 638) = 438306

GCD(687, 638) = ( 687 x 638 ) / 438306

= 687 / 638

= 687

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

So, Greatest Common Divisor of 687, 638, 651, 372 is 1
