Given numbers are 205, 556, 813

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

Apply this formula for all numbers.

Step1:

LCM(205, 556) = 113980

GCD(205, 556) = ( 205 x 556 ) / 113980

= 205 / 556

= 205

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 205, 556, 813 is 1
