Given numbers are 173, 855, 930, 390

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

Apply this formula for all numbers.

Step1:

LCM(173, 855) = 147915

GCD(173, 855) = ( 173 x 855 ) / 147915

= 173 / 855

= 173

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 173, 855, 930, 390 is 1
