Given numbers are 205, 811, 855

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

Apply this formula for all numbers.

Step1:

LCM(205, 811) = 166255

GCD(205, 811) = ( 205 x 811 ) / 166255

= 205 / 811

= 205

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 205, 811, 855 is 1
