Given numbers are 788, 671, 656, 120

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

Prime factors of 671 are 11 x 61

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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 788, 671, 656, 120

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

Apply this formula for all numbers.

Step1:

LCM(788, 671) = 528748

GCD(788, 671) = ( 788 x 671 ) / 528748

= 788 / 671

= 788

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 120) = 120

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

= 1 / 120

= 1

So, Greatest Common Divisor of 788, 671, 656, 120 is 1
