We found the divisors of 83, 66, 79, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 83, 66, 79, 64 is 1.

Therefore, GCD of numbers 83, 66, 79, 64 is 1

Given Input Data is 83, 66, 79, 64

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

Prime Factorization of 83 is 83

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 79 is 79

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

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(83, 66) = 5478

GCD(83, 66) = ( 83 x 66 ) / 5478

GCD(83, 66) = 5478 / 5478

GCD(83, 66) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

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 83, 66, 79, 64 is 1
