    Ans is a)3013
    LCM = 504
    Then we will try the values from 1-9 in the form of 504*k-11/23
    Subsituting k=6 we will get 504*6-11/23 i.e 3024-11/23 here we get remainder 0 so the number is 3013.

    LCM = 504 and difference btw divisor and remainder are: 11...lcm-diff/23...504-11/23 put the least value of k which is completely div of 23 .. 504k-11/23...Put k=1=>504-11/23=493/23(the value is not divisible of 23)...Put k=2=>504(2)-11/23=>1008-11/23=>997/23(not completely divisible of 23).. Put k=3,4,5....They are not completely divisible of 23... Put k=6=>504*6-11/23=>3024-11/23=>3013/23 is completely divisible of 23, So Option No1=>3013
