Greatest Common Divisior
We found the divisors of 15, 4, 99, 99 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 15, 4, 99, 99 is 1.
Therefore, GCD of numbers 15, 4, 99, 99 is 1
Given Input Data is 15, 4, 99, 99
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 15 is 3 x 5
Prime Factorization of 4 is 2 x 2
Prime Factorization of 99 is 3 x 3 x 11
Prime Factorization of 99 is 3 x 3 x 11
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 15, 4, 99, 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(15, 4) = 60
GCD(15, 4) = ( 15 x 4 ) / 60
GCD(15, 4) = 60 / 60
GCD(15, 4) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
GCD(1, 99) = 99 / 99
GCD(1, 99) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
GCD(1, 99) = 99 / 99
GCD(1, 99) = 1
GCD of 15, 4, 99, 99 is 1
