Greatest Common Divisior

We found the divisors of 21, 57, 92, 41 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 21, 57, 92, 41 is 1.

Therefore, GCD of numbers 21, 57, 92, 41 is 1

Given Input Data is 21, 57, 92, 41

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 57 is 3 x 19

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 41 is 41

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(21, 57) = 399

GCD(21, 57) = ( 21 x 57 ) / 399

GCD(21, 57) = 1197 / 399

GCD(21, 57) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 92

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

LCM(3, 92) = 276

GCD(3, 92) = ( 3 x 92 ) / 276

GCD(3, 92) = 276 / 276

GCD(3, 92) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 41

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

LCM(1, 41) = 41

GCD(1, 41) = ( 1 x 41 ) / 41

GCD(1, 41) = 41 / 41

GCD(1, 41) = 1

GCD of 21, 57, 92, 41 is 1
