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

Apply this formula for all numbers.

Step1:

LCM(173, 424) = 73352

GCD(173, 424) = ( 173 x 424 ) / 73352

= 173 / 424

= 173

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 173, 424, 639 is 1
