Given numbers are 172, 345, 191

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

Apply this formula for all numbers.

Step1:

LCM(172, 345) = 59340

GCD(172, 345) = ( 172 x 345 ) / 59340

= 172 / 345

= 172

Step2:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 172, 345, 191 is 1
