Given numbers are 490, 868, 77, 317

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

Apply this formula for all numbers.

Step1:

LCM(490, 868) = 30380

GCD(490, 868) = ( 490 x 868 ) / 30380

= 490 / 868

= 490

Step2:

LCM(14, 77) = 154

GCD(14, 77) = ( 14 x 77 ) / 154

= 14 / 77

= 14

Step3:

LCM(7, 317) = 2219

GCD(7, 317) = ( 7 x 317 ) / 2219

= 7 / 317

= 7

So, Greatest Common Divisor of 490, 868, 77, 317 is 1
