Given numbers are 686, 191, 237, 456

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 191 are 191

Prime factors of 237 are 3 x 79

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 686, 191, 237, 456

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(686, 191) = 131026

GCD(686, 191) = ( 686 x 191 ) / 131026

= 686 / 191

= 686

Step2:

LCM(1, 237) = 237

GCD(1, 237) = ( 1 x 237 ) / 237

= 1 / 237

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 686, 191, 237, 456 is 1
