Given Input Data is 957, 870, 218

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 218 is 2 x 109

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(957, 870) = 9570

GCD(957, 870) = ( 957 x 870 ) / 9570

GCD(957, 870) = 832590 / 9570

GCD(957, 870) = 87

Step2:

Here we consider the GCD from the above i.e. 87 as first number and the next as 218

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

LCM(87, 218) = 18966

GCD(87, 218) = ( 87 x 218 ) / 18966

GCD(87, 218) = 18966 / 18966

GCD(87, 218) = 1

GCD of 957, 870, 218 is 1
