Given numbers are 790, 117, 632, 420

The list of prime factors of all numbers are

Prime factors of 790 are 2 x 5 x 79

Prime factors of 117 are 3 x 3 x 13

Prime factors of 632 are 2 x 2 x 2 x 79

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 790, 117, 632, 420

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

Apply this formula for all numbers.

Step1:

LCM(790, 117) = 92430

GCD(790, 117) = ( 790 x 117 ) / 92430

= 790 / 117

= 790

Step2:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 790, 117, 632, 420 is 1
