Greatest Common Divisior

We found the divisors of 91, 2, 32, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 91, 2, 32, 19 is 1.

Therefore, GCD of numbers 91, 2, 32, 19 is 1

Given Input Data is 91, 2, 32, 19

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 2 is 2

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 19 is 19

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, 2) = 182

GCD(91, 2) = ( 91 x 2 ) / 182

GCD(91, 2) = 182 / 182

GCD(91, 2) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 32

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

LCM(1, 32) = 32

GCD(1, 32) = ( 1 x 32 ) / 32

GCD(1, 32) = 32 / 32

GCD(1, 32) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

GCD of 91, 2, 32, 19 is 1
