Question

Find the least multiple of 23 which when divided by 18

Answer 1

Answer:

The LCM of 18, 21 and 24 is 504 and if we add -11 to it (i. e. subtract 11 from it), we get 493 and this is the required number that leaves the remainders 7, 10 and 13 with the divisors 18, 21 and 24 respectively. But, we also want such a number to be completely divisoble by 23
