Given numbers are 663, 309, 340, 839

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

Apply this formula for all numbers.

Step1:

LCM(663, 309) = 68289

GCD(663, 309) = ( 663 x 309 ) / 68289

= 663 / 309

= 663

Step2:

LCM(3, 340) = 1020

GCD(3, 340) = ( 3 x 340 ) / 1020

= 3 / 340

= 3

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 663, 309, 340, 839 is 1
