Given numbers are 687, 810, 313, 890

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 313 are 313

Prime factors of 890 are 2 x 5 x 89

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

Given numbers are 687, 810, 313, 890

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

Apply this formula for all numbers.

Step1:

LCM(687, 810) = 185490

GCD(687, 810) = ( 687 x 810 ) / 185490

= 687 / 810

= 687

Step2:

LCM(3, 313) = 939

GCD(3, 313) = ( 3 x 313 ) / 939

= 3 / 313

= 3

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 687, 810, 313, 890 is 1
