Given numbers are 290, 289, 890

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

Apply this formula for all numbers.

Step1:

LCM(290, 289) = 83810

GCD(290, 289) = ( 290 x 289 ) / 83810

= 290 / 289

= 290

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 290, 289, 890 is 1
