Given numbers are 637, 828, 390, 718

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 718 are 2 x 359

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

Given numbers are 637, 828, 390, 718

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

Apply this formula for all numbers.

Step1:

LCM(637, 828) = 527436

GCD(637, 828) = ( 637 x 828 ) / 527436

= 637 / 828

= 637

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 637, 828, 390, 718 is 1
