Given Input Data is 548, 424, 143

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

Prime Factorization of 548 is 2 x 2 x 137

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 143 is 11 x 13

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(548, 424) = 58088

GCD(548, 424) = ( 548 x 424 ) / 58088

GCD(548, 424) = 232352 / 58088

GCD(548, 424) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 143

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

LCM(4, 143) = 572

GCD(4, 143) = ( 4 x 143 ) / 572

GCD(4, 143) = 572 / 572

GCD(4, 143) = 1

GCD of 548, 424, 143 is 1
