Given numbers are 628, 121, 749, 504

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 121 are 11 x 11

Prime factors of 749 are 7 x 107

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

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

Given numbers are 628, 121, 749, 504

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

Apply this formula for all numbers.

Step1:

LCM(628, 121) = 75988

GCD(628, 121) = ( 628 x 121 ) / 75988

= 628 / 121

= 628

Step2:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

Step3:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

So, Greatest Common Divisor of 628, 121, 749, 504 is 1
