Given numbers are 420, 114, 557, 129

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 114 are 2 x 3 x 19

Prime factors of 557 are 557

Prime factors of 129 are 3 x 43

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

Given numbers are 420, 114, 557, 129

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

Apply this formula for all numbers.

Step1:

LCM(420, 114) = 7980

GCD(420, 114) = ( 420 x 114 ) / 7980

= 420 / 114

= 420

Step2:

LCM(6, 557) = 3342

GCD(6, 557) = ( 6 x 557 ) / 3342

= 6 / 557

= 6

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 420, 114, 557, 129 is 1
