So the Greatest Common Divisior 81, 50, 72 is 1.
Therefore, GCD of numbers 81, 50, 72 is 1
Given Input Data is 81, 50, 72
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 50 is 2 x 5 x 5
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 81, 50, 72 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(81, 50) = 4050
GCD(81, 50) = ( 81 x 50 ) / 4050
GCD(81, 50) = 4050 / 4050
GCD(81, 50) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
GCD(1, 72) = 72 / 72
GCD(1, 72) = 1
GCD of 81, 50, 72 is 1
