Given numbers are 287, 676, 790, 831

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 790 are 2 x 5 x 79

Prime factors of 831 are 3 x 277

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

Given numbers are 287, 676, 790, 831

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

Apply this formula for all numbers.

Step1:

LCM(287, 676) = 194012

GCD(287, 676) = ( 287 x 676 ) / 194012

= 287 / 676

= 287

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 287, 676, 790, 831 is 1
