Given numbers are 634, 355, 490, 418

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 355 are 5 x 71

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 634, 355, 490, 418

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

Apply this formula for all numbers.

Step1:

LCM(634, 355) = 225070

GCD(634, 355) = ( 634 x 355 ) / 225070

= 634 / 355

= 634

Step2:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 634, 355, 490, 418 is 1
