Given numbers are 637, 728, 251, 511

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 251 are 251

Prime factors of 511 are 7 x 73

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

Given numbers are 637, 728, 251, 511

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

Apply this formula for all numbers.

Step1:

LCM(637, 728) = 5096

GCD(637, 728) = ( 637 x 728 ) / 5096

= 637 / 728

= 637

Step2:

LCM(91, 251) = 22841

GCD(91, 251) = ( 91 x 251 ) / 22841

= 91 / 251

= 91

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 637, 728, 251, 511 is 1
