Given numbers are 393, 861, 904, 260

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

Apply this formula for all numbers.

Step1:

LCM(393, 861) = 112791

GCD(393, 861) = ( 393 x 861 ) / 112791

= 393 / 861

= 393

Step2:

LCM(3, 904) = 2712

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

= 3 / 904

= 3

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 393, 861, 904, 260 is 1
