Given numbers are 721, 604, 172

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

Apply this formula for all numbers.

Step1:

LCM(721, 604) = 435484

GCD(721, 604) = ( 721 x 604 ) / 435484

= 721 / 604

= 721

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 721, 604, 172 is 1
