Therefore, GCD of numbers 709, 210, 615 is 1

Given Input Data is 709, 210, 615

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

Prime Factorization of 709 is 709

Prime Factorization of 210 is 2 x 3 x 5 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(709, 210) = 148890

GCD(709, 210) = ( 709 x 210 ) / 148890

GCD(709, 210) = 148890 / 148890

GCD(709, 210) = 1

Step2:

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 709, 210, 615 is 1
