Given numbers are 856, 730, 449

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

Apply this formula for all numbers.

Step1:

LCM(856, 730) = 312440

GCD(856, 730) = ( 856 x 730 ) / 312440

= 856 / 730

= 856

Step2:

LCM(2, 449) = 898

GCD(2, 449) = ( 2 x 449 ) / 898

= 2 / 449

= 2

So, Greatest Common Divisor of 856, 730, 449 is 1
