Therefore, GCD of numbers 715, 209, 904, 577 is 1

Given Input Data is 715, 209, 904, 577

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 209 is 11 x 19

Prime Factorization of 904 is 2 x 2 x 2 x 113

Prime Factorization of 577 is 577

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(715, 209) = 13585

GCD(715, 209) = ( 715 x 209 ) / 13585

GCD(715, 209) = 149435 / 13585

GCD(715, 209) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 904

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

LCM(11, 904) = 9944

GCD(11, 904) = ( 11 x 904 ) / 9944

GCD(11, 904) = 9944 / 9944

GCD(11, 904) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 577

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

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

GCD(1, 577) = 577 / 577

GCD(1, 577) = 1

GCD of 715, 209, 904, 577 is 1
