We found the divisors of 373, 237, 21, 168 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 373, 237, 21, 168 is 1.

Therefore, GCD of numbers 373, 237, 21, 168 is 1

Given Input Data is 373, 237, 21, 168

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

Prime Factorization of 373 is 373

Prime Factorization of 237 is 3 x 79

Prime Factorization of 21 is 3 x 7

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

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(373, 237) = 88401

GCD(373, 237) = ( 373 x 237 ) / 88401

GCD(373, 237) = 88401 / 88401

GCD(373, 237) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 168

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

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

GCD(1, 168) = 168 / 168

GCD(1, 168) = 1

GCD of 373, 237, 21, 168 is 1
