Therefore, GCD of numbers 247, 252, 159 is 1

Given Input Data is 247, 252, 159

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

Prime Factorization of 247 is 13 x 19

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 159 is 3 x 53

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(247, 252) = 62244

GCD(247, 252) = ( 247 x 252 ) / 62244

GCD(247, 252) = 62244 / 62244

GCD(247, 252) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 159

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

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

GCD(1, 159) = 159 / 159

GCD(1, 159) = 1

GCD of 247, 252, 159 is 1
