Therefore, GCD of numbers 747, 626, 285 is 1

Given Input Data is 747, 626, 285

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 626 is 2 x 313

Prime Factorization of 285 is 3 x 5 x 19

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, 626) = 467622

GCD(747, 626) = ( 747 x 626 ) / 467622

GCD(747, 626) = 467622 / 467622

GCD(747, 626) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 285

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

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

GCD(1, 285) = 285 / 285

GCD(1, 285) = 1

GCD of 747, 626, 285 is 1
