Given numbers are 831, 280, 299, 687

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 299 are 13 x 23

Prime factors of 687 are 3 x 229

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

Given numbers are 831, 280, 299, 687

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

Apply this formula for all numbers.

Step1:

LCM(831, 280) = 232680

GCD(831, 280) = ( 831 x 280 ) / 232680

= 831 / 280

= 831

Step2:

LCM(1, 299) = 299

GCD(1, 299) = ( 1 x 299 ) / 299

= 1 / 299

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 831, 280, 299, 687 is 1
