Given numbers are 637, 518, 421, 474

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 518 are 2 x 7 x 37

Prime factors of 421 are 421

Prime factors of 474 are 2 x 3 x 79

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

Given numbers are 637, 518, 421, 474

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

Apply this formula for all numbers.

Step1:

LCM(637, 518) = 47138

GCD(637, 518) = ( 637 x 518 ) / 47138

= 637 / 518

= 637

Step2:

LCM(7, 421) = 2947

GCD(7, 421) = ( 7 x 421 ) / 2947

= 7 / 421

= 7

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 637, 518, 421, 474 is 1
