Greatest Common Divisior

We found the divisors of 91, 43, 47 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 91, 43, 47 is 1.

Therefore, GCD of numbers 91, 43, 47 is 1

Given Input Data is 91, 43, 47

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 43 is 43

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(91, 43) = 3913

GCD(91, 43) = ( 91 x 43 ) / 3913

GCD(91, 43) = 3913 / 3913

GCD(91, 43) = 1

Step2:

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 91, 43, 47 is 1
