Given Input Data is 650, 975, 63, 615

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

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 615 is 3 x 5 x 41

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(650, 975) = 1950

GCD(650, 975) = ( 650 x 975 ) / 1950

GCD(650, 975) = 633750 / 1950

GCD(650, 975) = 325

Step2:

Here we consider the GCD from the above i.e. 325 as first number and the next as 63

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

LCM(325, 63) = 20475

GCD(325, 63) = ( 325 x 63 ) / 20475

GCD(325, 63) = 20475 / 20475

GCD(325, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 615

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

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

GCD(1, 615) = 615 / 615

GCD(1, 615) = 1

GCD of 650, 975, 63, 615 is 1
