Given Input Data is 621, 387, 562

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

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 562 is 2 x 281

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(621, 387) = 26703

GCD(621, 387) = ( 621 x 387 ) / 26703

GCD(621, 387) = 240327 / 26703

GCD(621, 387) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 562

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

LCM(9, 562) = 5058

GCD(9, 562) = ( 9 x 562 ) / 5058

GCD(9, 562) = 5058 / 5058

GCD(9, 562) = 1

GCD of 621, 387, 562 is 1
