Given Input Data is 147, 657, 841

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 841 is 29 x 29

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(147, 657) = 32193

GCD(147, 657) = ( 147 x 657 ) / 32193

GCD(147, 657) = 96579 / 32193

GCD(147, 657) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 841

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

LCM(3, 841) = 2523

GCD(3, 841) = ( 3 x 841 ) / 2523

GCD(3, 841) = 2523 / 2523

GCD(3, 841) = 1

GCD of 147, 657, 841 is 1
