Given Input Data is 74, 90, 99
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 74 is 2 x 37
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 99 is 3 x 3 x 11

Finding GCD of 74, 90, 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(74, 90) = 3330
GCD(74, 90) = ( 74 x 90 ) / 3330
GCD(74, 90) = 6660 / 3330
GCD(74, 90) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 99) = 198
GCD(2, 99) = ( 2 x 99 ) / 198
GCD(2, 99) = 198 / 198
GCD(2, 99) = 1
GCD of 74, 90, 99 is 1
