Given numbers are 120, 646, 317, 744

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 646 are 2 x 17 x 19

Prime factors of 317 are 317

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

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

Given numbers are 120, 646, 317, 744

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

Apply this formula for all numbers.

Step1:

LCM(120, 646) = 38760

GCD(120, 646) = ( 120 x 646 ) / 38760

= 120 / 646

= 120

Step2:

LCM(2, 317) = 634

GCD(2, 317) = ( 2 x 317 ) / 634

= 2 / 317

= 2

Step3:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

So, Greatest Common Divisor of 120, 646, 317, 744 is 1
