Given numbers are 646, 903, 931, 120

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 903 are 3 x 7 x 43

Prime factors of 931 are 7 x 7 x 19

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

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

Given numbers are 646, 903, 931, 120

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

Apply this formula for all numbers.

Step1:

LCM(646, 903) = 583338

GCD(646, 903) = ( 646 x 903 ) / 583338

= 646 / 903

= 646

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 646, 903, 931, 120 is 1
