Given a number N and a number K, the task is to find the largest number smaller than or equal to N which is divisible by K.
Input: N = 45, K = 6 Output: 42 42 is the largest number smaller than or equal to 45 which is divisible by 6. Input: N = 11, K = 3 Output: 9
Approach: The idea is to divide the N by K. If the remainder is 0 then print N else print N – remainder.
Below is the implementation of the above approach:
Largest number smaller than or equal to 45 that is divisible by 6 is 42
- Largest number smaller than or equal to n and digits in non-decreasing order
- Largest smaller number possible using only one swap operation
- Find largest number smaller than N with same set of digits
- Largest K digit number divisible by X
- Largest number divisible by 90 that can be made using 0 and 5
- Largest number with the given set of N digits that is divisible by 2, 3 and 5
- C++ Program for Largest K digit number divisible by X
- Largest N digit number divisible by given three numbers
- Largest Divisor of a Number not divisible by a perfect square
- Sum of largest divisible powers of p (a prime number) in a range
