Greatest Common Divisior

We found the divisors of 237, 687, 80, 154 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 237, 687, 80, 154 is 1.

Therefore, GCD of numbers 237, 687, 80, 154 is 1

Given Input Data is 237, 687, 80, 154

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

Prime Factorization of 237 is 3 x 79

Prime Factorization of 687 is 3 x 229

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 154 is 2 x 7 x 11

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(237, 687) = 54273

GCD(237, 687) = ( 237 x 687 ) / 54273

GCD(237, 687) = 162819 / 54273

GCD(237, 687) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 80

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

LCM(3, 80) = 240

GCD(3, 80) = ( 3 x 80 ) / 240

GCD(3, 80) = 240 / 240

GCD(3, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 154

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

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

GCD(1, 154) = 154 / 154

GCD(1, 154) = 1

GCD of 237, 687, 80, 154 is 1
