Given numbers are 687, 256, 190

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 190 are 2 x 5 x 19

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

Given numbers are 687, 256, 190

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

Apply this formula for all numbers.

Step1:

LCM(687, 256) = 175872

GCD(687, 256) = ( 687 x 256 ) / 175872

= 687 / 256

= 687

Step2:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 687, 256, 190 is 1
