Greatest Common Divisior

We found the divisors of 79, 11, 65, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 79, 11, 65, 47 is 1.

Therefore, GCD of numbers 79, 11, 65, 47 is 1

Given Input Data is 79, 11, 65, 47

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

Prime Factorization of 79 is 79

Prime Factorization of 11 is 11

Prime Factorization of 65 is 5 x 13

Prime Factorization of 47 is 47

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, 11) = 869

GCD(79, 11) = ( 79 x 11 ) / 869

GCD(79, 11) = 869 / 869

GCD(79, 11) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 47

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

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

GCD(1, 47) = 47 / 47

GCD(1, 47) = 1

GCD of 79, 11, 65, 47 is 1
