Therefore, GCD of numbers 419, 660, 728 is 1

Given Input Data is 419, 660, 728

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

Prime Factorization of 419 is 419

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

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(419, 660) = 276540

GCD(419, 660) = ( 419 x 660 ) / 276540

GCD(419, 660) = 276540 / 276540

GCD(419, 660) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 728

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

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

GCD(1, 728) = 728 / 728

GCD(1, 728) = 1

GCD of 419, 660, 728 is 1
