We found the divisors of 687, 686, 277, 666 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 687, 686, 277, 666 is 1.

Therefore, GCD of numbers 687, 686, 277, 666 is 1

Given Input Data is 687, 686, 277, 666

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

Prime Factorization of 687 is 3 x 229

Prime Factorization of 686 is 2 x 7 x 7 x 7

Prime Factorization of 277 is 277

Prime Factorization of 666 is 2 x 3 x 3 x 37

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(687, 686) = 471282

GCD(687, 686) = ( 687 x 686 ) / 471282

GCD(687, 686) = 471282 / 471282

GCD(687, 686) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 277

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

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

GCD(1, 277) = 277 / 277

GCD(1, 277) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 666

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

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

GCD(1, 666) = 666 / 666

GCD(1, 666) = 1

GCD of 687, 686, 277, 666 is 1
