Given numbers are 795, 351, 220, 420

The list of prime factors of all numbers are

Prime factors of 795 are 3 x 5 x 53

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 220 are 2 x 2 x 5 x 11

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 795, 351, 220, 420

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

Apply this formula for all numbers.

Step1:

LCM(795, 351) = 93015

GCD(795, 351) = ( 795 x 351 ) / 93015

= 795 / 351

= 795

Step2:

LCM(3, 220) = 660

GCD(3, 220) = ( 3 x 220 ) / 660

= 3 / 220

= 3

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 795, 351, 220, 420 is 1
