Given numbers are 631, 845, 77, 120

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 845 are 5 x 13 x 13

Prime factors of 77 are 7 x 11

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 631, 845, 77, 120

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

Apply this formula for all numbers.

Step1:

LCM(631, 845) = 533195

GCD(631, 845) = ( 631 x 845 ) / 533195

= 631 / 845

= 631

Step2:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

Step3:

LCM(1, 120) = 120

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

= 1 / 120

= 1

So, Greatest Common Divisor of 631, 845, 77, 120 is 1
