We found the divisors of 47, 39, 13, 22 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 39, 13, 22 is 1.

Therefore, GCD of numbers 47, 39, 13, 22 is 1

Given Input Data is 47, 39, 13, 22

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

Prime Factorization of 47 is 47

Prime Factorization of 39 is 3 x 13

Prime Factorization of 13 is 13

Prime Factorization of 22 is 2 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(47, 39) = 1833

GCD(47, 39) = ( 47 x 39 ) / 1833

GCD(47, 39) = 1833 / 1833

GCD(47, 39) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 13

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

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

GCD(1, 13) = 13 / 13

GCD(1, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 22

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

LCM(1, 22) = 22

GCD(1, 22) = ( 1 x 22 ) / 22

GCD(1, 22) = 22 / 22

GCD(1, 22) = 1

GCD of 47, 39, 13, 22 is 1
