Given Input Data is 396, 261, 137

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

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 137 is 137

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(396, 261) = 11484

GCD(396, 261) = ( 396 x 261 ) / 11484

GCD(396, 261) = 103356 / 11484

GCD(396, 261) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 137

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

LCM(9, 137) = 1233

GCD(9, 137) = ( 9 x 137 ) / 1233

GCD(9, 137) = 1233 / 1233

GCD(9, 137) = 1

GCD of 396, 261, 137 is 1
