Given numbers are 221, 556, 418

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

Apply this formula for all numbers.

Step1:

LCM(221, 556) = 122876

GCD(221, 556) = ( 221 x 556 ) / 122876

= 221 / 556

= 221

Step2:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 221, 556, 418 is 1
