Given Input Data is 798, 957, 621

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

Prime Factorization of 798 is 2 x 3 x 7 x 19

Prime Factorization of 957 is 3 x 11 x 29

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(798, 957) = 254562

GCD(798, 957) = ( 798 x 957 ) / 254562

GCD(798, 957) = 763686 / 254562

GCD(798, 957) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 621

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

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

GCD(3, 621) = 1863 / 621

GCD(3, 621) = 3

GCD of 798, 957, 621 is 3
