Given Input Data is 60, 63, 15
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 60 is 2 x 2 x 3 x 5
Prime Factorization of 63 is 3 x 3 x 7
Prime Factorization of 15 is 3 x 5

Finding GCD of 60, 63, 15 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(60, 63) = 1260
GCD(60, 63) = ( 60 x 63 ) / 1260
GCD(60, 63) = 3780 / 1260
GCD(60, 63) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 15) = 15
GCD(3, 15) = ( 3 x 15 ) / 15
GCD(3, 15) = 45 / 15
GCD(3, 15) = 3
GCD of 60, 63, 15 is 3
