Therefore, GCD of numbers 15, 550, 721, 332 is 1

Given Input Data is 15, 550, 721, 332

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 721 is 7 x 103

Prime Factorization of 332 is 2 x 2 x 83

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(15, 550) = 1650

GCD(15, 550) = ( 15 x 550 ) / 1650

GCD(15, 550) = 8250 / 1650

GCD(15, 550) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 721

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

LCM(5, 721) = 3605

GCD(5, 721) = ( 5 x 721 ) / 3605

GCD(5, 721) = 3605 / 3605

GCD(5, 721) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 332

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

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

GCD(1, 332) = 332 / 332

GCD(1, 332) = 1

GCD of 15, 550, 721, 332 is 1
