Given numbers are 210, 243, 903, 138

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

Apply this formula for all numbers.

Step1:

LCM(210, 243) = 17010

GCD(210, 243) = ( 210 x 243 ) / 17010

= 210 / 243

= 210

Step2:

LCM(3, 903) = 903

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

= 3 / 903

= 3

Step3:

LCM(3, 138) = 138

GCD(3, 138) = ( 3 x 138 ) / 138

= 3 / 138

= 3

So, Greatest Common Divisor of 210, 243, 903, 138 is 3
