We found the divisors of 238, 451, 40, 244 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 238, 451, 40, 244 is 1.

Therefore, GCD of numbers 238, 451, 40, 244 is 1

Given Input Data is 238, 451, 40, 244

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

Prime Factorization of 238 is 2 x 7 x 17

Prime Factorization of 451 is 11 x 41

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 244 is 2 x 2 x 61

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(238, 451) = 107338

GCD(238, 451) = ( 238 x 451 ) / 107338

GCD(238, 451) = 107338 / 107338

GCD(238, 451) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 244

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

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

GCD(1, 244) = 244 / 244

GCD(1, 244) = 1

GCD of 238, 451, 40, 244 is 1
