Given numbers are 449, 289, 283, 140

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

Apply this formula for all numbers.

Step1:

LCM(449, 289) = 129761

GCD(449, 289) = ( 449 x 289 ) / 129761

= 449 / 289

= 449

Step2:

LCM(1, 283) = 283

GCD(1, 283) = ( 1 x 283 ) / 283

= 1 / 283

= 1

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 449, 289, 283, 140 is 1
