Given numbers are 813, 422, 290

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

Apply this formula for all numbers.

Step1:

LCM(813, 422) = 343086

GCD(813, 422) = ( 813 x 422 ) / 343086

= 813 / 422

= 813

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 813, 422, 290 is 1
