Given Input Data is 639, 954, 783

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 954 is 2 x 3 x 3 x 53

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

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(639, 954) = 67734

GCD(639, 954) = ( 639 x 954 ) / 67734

GCD(639, 954) = 609606 / 67734

GCD(639, 954) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 783

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

LCM(9, 783) = 783

GCD(9, 783) = ( 9 x 783 ) / 783

GCD(9, 783) = 7047 / 783

GCD(9, 783) = 9

GCD of 639, 954, 783 is 9
