Given numbers are 819, 221, 205, 558

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

Apply this formula for all numbers.

Step1:

LCM(819, 221) = 13923

GCD(819, 221) = ( 819 x 221 ) / 13923

= 819 / 221

= 819

Step2:

LCM(13, 205) = 2665

GCD(13, 205) = ( 13 x 205 ) / 2665

= 13 / 205

= 13

Step3:

LCM(1, 558) = 558

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

= 1 / 558

= 1

So, Greatest Common Divisor of 819, 221, 205, 558 is 1
