Given Input Data is 678, 153, 249

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

Prime Factorization of 678 is 2 x 3 x 113

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 249 is 3 x 83

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(678, 153) = 34578

GCD(678, 153) = ( 678 x 153 ) / 34578

GCD(678, 153) = 103734 / 34578

GCD(678, 153) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 249

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

LCM(3, 249) = 249

GCD(3, 249) = ( 3 x 249 ) / 249

GCD(3, 249) = 747 / 249

GCD(3, 249) = 3

GCD of 678, 153, 249 is 3
