Given numbers are 199, 645, 558

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

Apply this formula for all numbers.

Step1:

LCM(199, 645) = 128355

GCD(199, 645) = ( 199 x 645 ) / 128355

= 199 / 645

= 199

Step2:

LCM(1, 558) = 558

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

= 1 / 558

= 1

So, Greatest Common Divisor of 199, 645, 558 is 1
