Therefore, GCD of numbers 673, 255, 243 is 1

Given Input Data is 673, 255, 243

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

Prime Factorization of 673 is 673

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

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(673, 255) = 171615

GCD(673, 255) = ( 673 x 255 ) / 171615

GCD(673, 255) = 171615 / 171615

GCD(673, 255) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 243

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

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

GCD(1, 243) = 243 / 243

GCD(1, 243) = 1

GCD of 673, 255, 243 is 1
