So the Greatest Common Divisior 72, 45, 86 is 1.
Therefore, GCD of numbers 72, 45, 86 is 1
Given Input Data is 72, 45, 86
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
Prime Factorization of 45 is 3 x 3 x 5
Prime Factorization of 86 is 2 x 43
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 72, 45, 86 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(72, 45) = 360
GCD(72, 45) = ( 72 x 45 ) / 360
GCD(72, 45) = 3240 / 360
GCD(72, 45) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 86) = 774
GCD(9, 86) = ( 9 x 86 ) / 774
GCD(9, 86) = 774 / 774
GCD(9, 86) = 1
GCD of 72, 45, 86 is 1
