Given numbers are 957, 618, 620, 870

The list of prime factors of all numbers are

Prime factors of 957 are 3 x 11 x 29

Prime factors of 618 are 2 x 3 x 103

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 957, 618, 620, 870

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

Apply this formula for all numbers.

Step1:

LCM(957, 618) = 197142

GCD(957, 618) = ( 957 x 618 ) / 197142

= 957 / 618

= 957

Step2:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 957, 618, 620, 870 is 1
