Given numbers are 393, 447, 803, 404

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

Apply this formula for all numbers.

Step1:

LCM(393, 447) = 58557

GCD(393, 447) = ( 393 x 447 ) / 58557

= 393 / 447

= 393

Step2:

LCM(3, 803) = 2409

GCD(3, 803) = ( 3 x 803 ) / 2409

= 3 / 803

= 3

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 393, 447, 803, 404 is 1
