Given numbers are 390, 921, 591, 634

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 921 are 3 x 307

Prime factors of 591 are 3 x 197

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 390, 921, 591, 634

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

Apply this formula for all numbers.

Step1:

LCM(390, 921) = 119730

GCD(390, 921) = ( 390 x 921 ) / 119730

= 390 / 921

= 390

Step2:

LCM(3, 591) = 591

GCD(3, 591) = ( 3 x 591 ) / 591

= 3 / 591

= 3

Step3:

LCM(3, 634) = 1902

GCD(3, 634) = ( 3 x 634 ) / 1902

= 3 / 634

= 3

So, Greatest Common Divisor of 390, 921, 591, 634 is 1
