Given numbers are 221, 206, 558

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

Apply this formula for all numbers.

Step1:

LCM(221, 206) = 45526

GCD(221, 206) = ( 221 x 206 ) / 45526

= 221 / 206

= 221

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 221, 206, 558 is 1
