Given Input Data is 645, 219, 237

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 219 is 3 x 73

Prime Factorization of 237 is 3 x 79

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(645, 219) = 47085

GCD(645, 219) = ( 645 x 219 ) / 47085

GCD(645, 219) = 141255 / 47085

GCD(645, 219) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 237

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

LCM(3, 237) = 237

GCD(3, 237) = ( 3 x 237 ) / 237

GCD(3, 237) = 711 / 237

GCD(3, 237) = 3

GCD of 645, 219, 237 is 3
