Given numbers are 686, 846, 280

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

Apply this formula for all numbers.

Step1:

LCM(686, 846) = 290178

GCD(686, 846) = ( 686 x 846 ) / 290178

= 686 / 846

= 686

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

So, Greatest Common Divisor of 686, 846, 280 is 2
