Greatest Common Divisior

We found the divisors of 79, 31, 66 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 79, 31, 66 is 1.

Therefore, GCD of numbers 79, 31, 66 is 1

Given Input Data is 79, 31, 66

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

Prime Factorization of 79 is 79

Prime Factorization of 31 is 31

Prime Factorization of 66 is 2 x 3 x 11

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(79, 31) = 2449

GCD(79, 31) = ( 79 x 31 ) / 2449

GCD(79, 31) = 2449 / 2449

GCD(79, 31) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

GCD of 79, 31, 66 is 1
