Given numbers are 173, 645, 730

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

Apply this formula for all numbers.

Step1:

LCM(173, 645) = 111585

GCD(173, 645) = ( 173 x 645 ) / 111585

= 173 / 645

= 173

Step2:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 173, 645, 730 is 1
