Given Input Data is 75, 80, 99
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 75 is 3 x 5 x 5
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 99 is 3 x 3 x 11

Finding GCD of 75, 80, 99 using LCM Formula
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(75, 80) = 1200
GCD(75, 80) = ( 75 x 80 ) / 1200
GCD(75, 80) = 6000 / 1200
GCD(75, 80) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 99) = 495
GCD(5, 99) = ( 5 x 99 ) / 495
GCD(5, 99) = 495 / 495
GCD(5, 99) = 1
GCD of 75, 80, 99 is 1
