Given numbers are 627, 440, 398, 634

The list of prime factors of all numbers are

Prime factors of 627 are 3 x 11 x 19

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 398 are 2 x 199

Prime factors of 634 are 2 x 317

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

Given numbers are 627, 440, 398, 634

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

Apply this formula for all numbers.

Step1:

LCM(627, 440) = 25080

GCD(627, 440) = ( 627 x 440 ) / 25080

= 627 / 440

= 627

Step2:

LCM(11, 398) = 4378

GCD(11, 398) = ( 11 x 398 ) / 4378

= 11 / 398

= 11

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 627, 440, 398, 634 is 1
