Therefore, GCD of numbers 747, 220, 250 is 1

Given Input Data is 747, 220, 250

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

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 250 is 2 x 5 x 5 x 5

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(747, 220) = 164340

GCD(747, 220) = ( 747 x 220 ) / 164340

GCD(747, 220) = 164340 / 164340

GCD(747, 220) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 250

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

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

GCD(1, 250) = 250 / 250

GCD(1, 250) = 1

GCD of 747, 220, 250 is 1
