Given numbers are 628, 429, 455, 317

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

Apply this formula for all numbers.

Step1:

LCM(628, 429) = 269412

GCD(628, 429) = ( 628 x 429 ) / 269412

= 628 / 429

= 628

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 317) = 317

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

= 1 / 317

= 1

So, Greatest Common Divisor of 628, 429, 455, 317 is 1
