Given Input Data is 207, 399, 951

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 951 is 3 x 317

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(207, 399) = 27531

GCD(207, 399) = ( 207 x 399 ) / 27531

GCD(207, 399) = 82593 / 27531

GCD(207, 399) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 951

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

LCM(3, 951) = 951

GCD(3, 951) = ( 3 x 951 ) / 951

GCD(3, 951) = 2853 / 951

GCD(3, 951) = 3

GCD of 207, 399, 951 is 3
