Greatest Common Divisior

We found the divisors of 79, 12, 77, 33 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 79, 12, 77, 33 is 1.

Therefore, GCD of numbers 79, 12, 77, 33 is 1

Given Input Data is 79, 12, 77, 33

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

Prime Factorization of 79 is 79

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 77 is 7 x 11

Prime Factorization of 33 is 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, 12) = 948

GCD(79, 12) = ( 79 x 12 ) / 948

GCD(79, 12) = 948 / 948

GCD(79, 12) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 33

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

LCM(1, 33) = 33

GCD(1, 33) = ( 1 x 33 ) / 33

GCD(1, 33) = 33 / 33

GCD(1, 33) = 1

GCD of 79, 12, 77, 33 is 1
