Given Input Data is 783, 738, 639

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

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 738 is 2 x 3 x 3 x 41

Prime Factorization of 639 is 3 x 3 x 71

Highest common occurrences in the given inputs are 3²

Multiplying them we get the GCD as 9

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(783, 738) = 64206

GCD(783, 738) = ( 783 x 738 ) / 64206

GCD(783, 738) = 577854 / 64206

GCD(783, 738) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 639

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

LCM(9, 639) = 639

GCD(9, 639) = ( 9 x 639 ) / 639

GCD(9, 639) = 5751 / 639

GCD(9, 639) = 9

GCD of 783, 738, 639 is 9
