Therefore, GCD of numbers 39, 75, 99 is 3

Given Input Data is 39, 75, 99

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 99 is 3 x 3 x 11

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(39, 75) = 975

GCD(39, 75) = ( 39 x 75 ) / 975

GCD(39, 75) = 2925 / 975

GCD(39, 75) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 99

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

LCM(3, 99) = 99

GCD(3, 99) = ( 3 x 99 ) / 99

GCD(3, 99) = 297 / 99

GCD(3, 99) = 3

GCD of 39, 75, 99 is 3
