Therefore, GCD of numbers 581, 654, 285 is 1

Given Input Data is 581, 654, 285

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 654 is 2 x 3 x 109

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(581, 654) = 379974

GCD(581, 654) = ( 581 x 654 ) / 379974

GCD(581, 654) = 379974 / 379974

GCD(581, 654) = 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 581, 654, 285 is 1
