Given numbers are 286, 389, 406

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

Apply this formula for all numbers.

Step1:

LCM(286, 389) = 111254

GCD(286, 389) = ( 286 x 389 ) / 111254

= 286 / 389

= 286

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 286, 389, 406 is 1
