Given numbers are 855, 677, 217

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

Apply this formula for all numbers.

Step1:

LCM(855, 677) = 578835

GCD(855, 677) = ( 855 x 677 ) / 578835

= 855 / 677

= 855

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 855, 677, 217 is 1
