Given Input Data is 546, 129, 551

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

Prime Factorization of 546 is 2 x 3 x 7 x 13

Prime Factorization of 129 is 3 x 43

Prime Factorization of 551 is 19 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(546, 129) = 23478

GCD(546, 129) = ( 546 x 129 ) / 23478

GCD(546, 129) = 70434 / 23478

GCD(546, 129) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 551

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

LCM(3, 551) = 1653

GCD(3, 551) = ( 3 x 551 ) / 1653

GCD(3, 551) = 1653 / 1653

GCD(3, 551) = 1

GCD of 546, 129, 551 is 1
