Given numbers are 215, 209, 855

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

Apply this formula for all numbers.

Step1:

LCM(215, 209) = 44935

GCD(215, 209) = ( 215 x 209 ) / 44935

= 215 / 209

= 215

Step2:

LCM(1, 855) = 855

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

= 1 / 855

= 1

So, Greatest Common Divisor of 215, 209, 855 is 1
