Greatest Common Divisior

We found the divisors of 17, 3, 64, 91 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 17, 3, 64, 91 is 1.

Therefore, GCD of numbers 17, 3, 64, 91 is 1

Given Input Data is 17, 3, 64, 91

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

Prime Factorization of 17 is 17

Prime Factorization of 3 is 3

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 91 is 7 x 13

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(17, 3) = 51

GCD(17, 3) = ( 17 x 3 ) / 51

GCD(17, 3) = 51 / 51

GCD(17, 3) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 64

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

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

GCD(1, 64) = 64 / 64

GCD(1, 64) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

GCD of 17, 3, 64, 91 is 1
