Given numbers are 228, 417, 21, 903

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

Apply this formula for all numbers.

Step1:

LCM(228, 417) = 31692

GCD(228, 417) = ( 228 x 417 ) / 31692

= 228 / 417

= 228

Step2:

LCM(3, 21) = 21

GCD(3, 21) = ( 3 x 21 ) / 21

= 3 / 21

= 3

Step3:

LCM(3, 903) = 903

GCD(3, 903) = ( 3 x 903 ) / 903

= 3 / 903

= 3

So, Greatest Common Divisor of 228, 417, 21, 903 is 3
