Given numbers are 393, 630, 178, 317

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

Apply this formula for all numbers.

Step1:

LCM(393, 630) = 82530

GCD(393, 630) = ( 393 x 630 ) / 82530

= 393 / 630

= 393

Step2:

LCM(3, 178) = 534

GCD(3, 178) = ( 3 x 178 ) / 534

= 3 / 178

= 3

Step3:

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

= 1 / 317

= 1

So, Greatest Common Divisor of 393, 630, 178, 317 is 1
