GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 459) = 6885
GCD(405, 459) = ( 405 x 459 ) / 6885
= 405 / 459
= 405
Step2:
LCM(27, 234) = 702
GCD(27, 234) = ( 27 x 234 ) / 702
= 27 / 234
= 27
Step3:
LCM(9, 621) = 621
GCD(9, 621) = ( 9 x 621 ) / 621
= 9 / 621
= 9
So, Greatest Common Divisor of 405, 459, 234, 621 is 9
