Given numbers are 390, 634, 569, 317

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

Apply this formula for all numbers.

Step1:

LCM(390, 634) = 123630

GCD(390, 634) = ( 390 x 634 ) / 123630

= 390 / 634

= 390

Step2:

LCM(2, 569) = 1138

GCD(2, 569) = ( 2 x 569 ) / 1138

= 2 / 569

= 2

Step3:

LCM(1, 317) = 317

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

= 1 / 317

= 1

So, Greatest Common Divisor of 390, 634, 569, 317 is 1
