Greatest Common Divisior

We found the divisors of 221, 223, 24, 157 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 221, 223, 24, 157 is 1.

Therefore, GCD of numbers 221, 223, 24, 157 is 1

Given Input Data is 221, 223, 24, 157

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 223 is 223

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

Prime Factorization of 157 is 157

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(221, 223) = 49283

GCD(221, 223) = ( 221 x 223 ) / 49283

GCD(221, 223) = 49283 / 49283

GCD(221, 223) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 157

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

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

GCD(1, 157) = 157 / 157

GCD(1, 157) = 1

GCD of 221, 223, 24, 157 is 1
