Given Input Data is 552, 612, 621

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

Prime Factorization of 552 is 2 x 2 x 2 x 3 x 23

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(552, 612) = 28152

GCD(552, 612) = ( 552 x 612 ) / 28152

GCD(552, 612) = 337824 / 28152

GCD(552, 612) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 621

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

LCM(12, 621) = 2484

GCD(12, 621) = ( 12 x 621 ) / 2484

GCD(12, 621) = 7452 / 2484

GCD(12, 621) = 3

GCD of 552, 612, 621 is 3
