Given numbers are 173, 393, 259, 648

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

Apply this formula for all numbers.

Step1:

LCM(173, 393) = 67989

GCD(173, 393) = ( 173 x 393 ) / 67989

= 173 / 393

= 173

Step2:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 173, 393, 259, 648 is 1
