Given numbers are 686, 518, 872, 282

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

Apply this formula for all numbers.

Step1:

LCM(686, 518) = 25382

GCD(686, 518) = ( 686 x 518 ) / 25382

= 686 / 518

= 686

Step2:

LCM(14, 872) = 6104

GCD(14, 872) = ( 14 x 872 ) / 6104

= 14 / 872

= 14

Step3:

LCM(2, 282) = 282

GCD(2, 282) = ( 2 x 282 ) / 282

= 2 / 282

= 2

So, Greatest Common Divisor of 686, 518, 872, 282 is 2
