We found the divisors of 58, 72, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 58, 72, 47 is 1.

Therefore, GCD of numbers 58, 72, 47 is 1

Given Input Data is 58, 72, 47

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

Prime Factorization of 58 is 2 x 29

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

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(58, 72) = 2088

GCD(58, 72) = ( 58 x 72 ) / 2088

GCD(58, 72) = 4176 / 2088

GCD(58, 72) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 47

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

LCM(2, 47) = 94

GCD(2, 47) = ( 2 x 47 ) / 94

GCD(2, 47) = 94 / 94

GCD(2, 47) = 1

GCD of 58, 72, 47 is 1
