Given numbers are 672, 318, 243, 809

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

Apply this formula for all numbers.

Step1:

LCM(672, 318) = 35616

GCD(672, 318) = ( 672 x 318 ) / 35616

= 672 / 318

= 672

Step2:

LCM(6, 243) = 486

GCD(6, 243) = ( 6 x 243 ) / 486

= 6 / 243

= 6

Step3:

LCM(3, 809) = 2427

GCD(3, 809) = ( 3 x 809 ) / 2427

= 3 / 809

= 3

So, Greatest Common Divisor of 672, 318, 243, 809 is 1
