Greatest Common Divisior

We found the divisors of 84, 71, 91, 24 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 71, 91, 24 is 1.

Therefore, GCD of numbers 84, 71, 91, 24 is 1

Given Input Data is 84, 71, 91, 24

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 71 is 71

Prime Factorization of 91 is 7 x 13

Prime Factorization of 24 is 2 x 2 x 2 x 3

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(84, 71) = 5964

GCD(84, 71) = ( 84 x 71 ) / 5964

GCD(84, 71) = 5964 / 5964

GCD(84, 71) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 24

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

LCM(1, 24) = 24

GCD(1, 24) = ( 1 x 24 ) / 24

GCD(1, 24) = 24 / 24

GCD(1, 24) = 1

GCD of 84, 71, 91, 24 is 1
