MATLAB中的Smallest_multiple函数

Question

Hi I am having problems with the following function in Matlab. Can some please help? 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. Write a function called smallest_multiple that returns a uint64, the smallest positive number that is evenly divisible by all of the numbers from 1 to n where n is a positive integer scalar and is the only input argument of the function. If the result would be greater than what can be represented as a uint64, the function returns 0. (Inspired by Project Euler.)

Below is the code I wrote for the function but it gives error Feedback: Your function made an error for argument(s) 2

Your solution is _not_ correct.

Help please...

function [answer]=smallest_multiple(n)
limit = 1e10;

N = 20;

for i = N:N:limit

    for j = N:-1:1

    if mod(i,j) ~= 0

        break

    end

end

if j == 1

    answer = i;

    break

    end

end

fprintf('The smallest evenly divisible number is %.0d\n',answer)

Answer 1

Your function looks correct. However the argument you pass is a lowercase n instead of an uppercase N , which you use during your code.

So the correct function (with limit as argument) is

function [answer]=smallest_multiple(N,limit)

for i = N:N:limit

    for j = N:-1:1

        if mod(i,j) ~= 0
            break
        end

    end

    if j == 1
        answer = i;
        break
    end

end

fprintf('The smallest evenly divisible number is %.0d\n',answer)
