Given numbers are 420, 129, 875, 902

The list of prime factors of all numbers are

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

Prime factors of 129 are 3 x 43

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 902 are 2 x 11 x 41

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

Given numbers are 420, 129, 875, 902

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

Apply this formula for all numbers.

Step1:

LCM(420, 129) = 18060

GCD(420, 129) = ( 420 x 129 ) / 18060

= 420 / 129

= 420

Step2:

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

= 3 / 875

= 3

Step3:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

So, Greatest Common Divisor of 420, 129, 875, 902 is 1
