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

Apply this formula for all numbers.

Step1:

LCM(399, 172) = 68628

GCD(399, 172) = ( 399 x 172 ) / 68628

= 399 / 172

= 399

Step2:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 399, 172, 199 is 1
