Given numbers are 390, 638, 312, 601

The list of prime factors of all numbers are

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

Prime factors of 638 are 2 x 11 x 29

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 601 are 601

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

Given numbers are 390, 638, 312, 601

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

Apply this formula for all numbers.

Step1:

LCM(390, 638) = 124410

GCD(390, 638) = ( 390 x 638 ) / 124410

= 390 / 638

= 390

Step2:

LCM(2, 312) = 312

GCD(2, 312) = ( 2 x 312 ) / 312

= 2 / 312

= 2

Step3:

LCM(2, 601) = 1202

GCD(2, 601) = ( 2 x 601 ) / 1202

= 2 / 601

= 2

So, Greatest Common Divisor of 390, 638, 312, 601 is 1
