Given numbers are 686, 169, 424

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

Apply this formula for all numbers.

Step1:

LCM(686, 169) = 115934

GCD(686, 169) = ( 686 x 169 ) / 115934

= 686 / 169

= 686

Step2:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 686, 169, 424 is 1
