Given numbers are 420, 472, 612, 957

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 472 are 2 x 2 x 2 x 59

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 420, 472, 612, 957

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

Apply this formula for all numbers.

Step1:

LCM(420, 472) = 49560

GCD(420, 472) = ( 420 x 472 ) / 49560

= 420 / 472

= 420

Step2:

LCM(4, 612) = 612

GCD(4, 612) = ( 4 x 612 ) / 612

= 4 / 612

= 4

Step3:

LCM(4, 957) = 3828

GCD(4, 957) = ( 4 x 957 ) / 3828

= 4 / 957

= 4

So, Greatest Common Divisor of 420, 472, 612, 957 is 1
