Given numbers are 390, 645, 608, 119

The list of prime factors of all numbers are

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

Prime factors of 645 are 3 x 5 x 43

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 119 are 7 x 17

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

Given numbers are 390, 645, 608, 119

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

Apply this formula for all numbers.

Step1:

LCM(390, 645) = 16770

GCD(390, 645) = ( 390 x 645 ) / 16770

= 390 / 645

= 390

Step2:

LCM(15, 608) = 9120

GCD(15, 608) = ( 15 x 608 ) / 9120

= 15 / 608

= 15

Step3:

LCM(1, 119) = 119

GCD(1, 119) = ( 1 x 119 ) / 119

= 1 / 119

= 1

So, Greatest Common Divisor of 390, 645, 608, 119 is 1
