Given numbers are 637, 339, 630, 639

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 339 are 3 x 113

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 637, 339, 630, 639

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

Apply this formula for all numbers.

Step1:

LCM(637, 339) = 215943

GCD(637, 339) = ( 637 x 339 ) / 215943

= 637 / 339

= 637

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 637, 339, 630, 639 is 1
