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

Apply this formula for all numbers.

Step1:

LCM(449, 643) = 288707

GCD(449, 643) = ( 449 x 643 ) / 288707

= 449 / 643

= 449

Step2:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 449, 643, 519, 816 is 1
