GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(873, 231) = 67221
GCD(873, 231) = ( 873 x 231 ) / 67221
= 873 / 231
= 873
Step2:
LCM(3, 309) = 309
GCD(3, 309) = ( 3 x 309 ) / 309
= 3 / 309
= 3
Step3:
LCM(3, 405) = 405
GCD(3, 405) = ( 3 x 405 ) / 405
= 3 / 405
= 3
So, Greatest Common Divisor of 873, 231, 309, 405 is 3
