Given numbers are 317, 561, 808, 878

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

Apply this formula for all numbers.

Step1:

LCM(317, 561) = 177837

GCD(317, 561) = ( 317 x 561 ) / 177837

= 317 / 561

= 317

Step2:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 317, 561, 808, 878 is 1
