Given numbers are 447, 861, 904, 872

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

Apply this formula for all numbers.

Step1:

LCM(447, 861) = 128289

GCD(447, 861) = ( 447 x 861 ) / 128289

= 447 / 861

= 447

Step2:

LCM(3, 904) = 2712

GCD(3, 904) = ( 3 x 904 ) / 2712

= 3 / 904

= 3

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 447, 861, 904, 872 is 1
