So the Greatest Common Divisior 80, 69, 64 is 1.
Therefore, GCD of numbers 80, 69, 64 is 1
Given Input Data is 80, 69, 64
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 69 is 3 x 23
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 80, 69, 64 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(80, 69) = 5520
GCD(80, 69) = ( 80 x 69 ) / 5520
GCD(80, 69) = 5520 / 5520
GCD(80, 69) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
GCD of 80, 69, 64 is 1
