So the Greatest Common Divisior 68, 64, 79 is 1.

Therefore, GCD of numbers 68, 64, 79 is 1

Given Input Data is 68, 64, 79

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 79 is 79

The above numbers do not have any common prime factor. So GCD is 1

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(68, 64) = 1088

GCD(68, 64) = ( 68 x 64 ) / 1088

GCD(68, 64) = 4352 / 1088

GCD(68, 64) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 79

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(4, 79) = 316

GCD(4, 79) = ( 4 x 79 ) / 316

GCD(4, 79) = 316 / 316

GCD(4, 79) = 1

GCD of 68, 64, 79 is 1
