Given numbers are 289, 470, 449, 395

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

Apply this formula for all numbers.

Step1:

LCM(289, 470) = 135830

GCD(289, 470) = ( 289 x 470 ) / 135830

= 289 / 470

= 289

Step2:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 289, 470, 449, 395 is 1
