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

Apply this formula for all numbers.

Step1:

LCM(809, 890) = 720010

GCD(809, 890) = ( 809 x 890 ) / 720010

= 809 / 890

= 809

Step2:

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

= 1 / 17

= 1

So, Greatest Common Divisor of 809, 890, 17 is 1
