Given numbers are 342, 855, 411

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

Apply this formula for all numbers.

Step1:

LCM(342, 855) = 1710

GCD(342, 855) = ( 342 x 855 ) / 1710

= 342 / 855

= 342

Step2:

LCM(171, 411) = 23427

GCD(171, 411) = ( 171 x 411 ) / 23427

= 171 / 411

= 171

So, Greatest Common Divisor of 342, 855, 411 is 3
