Given numbers are 109, 209, 285

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

Apply this formula for all numbers.

Step1:

LCM(109, 209) = 22781

GCD(109, 209) = ( 109 x 209 ) / 22781

= 109 / 209

= 109

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 109, 209, 285 is 1
