Therefore, GCD of numbers 721, 974, 441 is 1

Given Input Data is 721, 974, 441

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 974 is 2 x 487

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(721, 974) = 702254

GCD(721, 974) = ( 721 x 974 ) / 702254

GCD(721, 974) = 702254 / 702254

GCD(721, 974) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 721, 974, 441 is 1
