Given numbers are 390, 602, 711, 638

The list of prime factors of all numbers are

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

Prime factors of 602 are 2 x 7 x 43

Prime factors of 711 are 3 x 3 x 79

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 390, 602, 711, 638

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

Apply this formula for all numbers.

Step1:

LCM(390, 602) = 117390

GCD(390, 602) = ( 390 x 602 ) / 117390

= 390 / 602

= 390

Step2:

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

= 2 / 711

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 390, 602, 711, 638 is 1
