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

Apply this formula for all numbers.

Step1:

LCM(903, 861) = 37023

GCD(903, 861) = ( 903 x 861 ) / 37023

= 903 / 861

= 903

Step2:

LCM(21, 189) = 189

GCD(21, 189) = ( 21 x 189 ) / 189

= 21 / 189

= 21

Step3:

LCM(21, 303) = 2121

GCD(21, 303) = ( 21 x 303 ) / 2121

= 21 / 303

= 21

So, Greatest Common Divisor of 903, 861, 189, 303 is 3
