Given numbers are 687, 312, 867, 817

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

Apply this formula for all numbers.

Step1:

LCM(687, 312) = 71448

GCD(687, 312) = ( 687 x 312 ) / 71448

= 687 / 312

= 687

Step2:

LCM(3, 867) = 867

GCD(3, 867) = ( 3 x 867 ) / 867

= 3 / 867

= 3

Step3:

LCM(3, 817) = 2451

GCD(3, 817) = ( 3 x 817 ) / 2451

= 3 / 817

= 3

So, Greatest Common Divisor of 687, 312, 867, 817 is 1
