Find the number of divisors of a given number using matlab

This post is to link all the methods for solving this problem, but here I will not write the solution but I will explain the mathematics behind the each method. Also I will provide you with the link to the solution which I have already written under each method I will state. Here it should be noted that the time mentioned at the end of this post is what I have observed on my PC and can be seen If you will execute the function for very long numbers.

Method 1

This method uses the simple technique of start from 1 and divide the given number, next 2 divide the number, and so on till the given number is reached. In the above looping if the number and the iterator number is divisible then increase the counter with 1 and after the complete execution of the program then return the counter value. This counter value will give you the number of divisors of the given number. You can see the program for method 1 here:

Method 2


This method is very simple. You can understand it easily by reading it here:
And to see the program visit the link here: (Note that the explanation of the mathematics behind the program and also the program is on the post page).

Method 3

This method is also simple if you will understand it. You can read about the mathematics behind this program here: 
And the program here: (Also note that the mathematics behind this program solving has been given in the post including the program section)

The time of execution for the above methods is as follows
Method 2 > Method 3 > Method 1

This is all about this post and see you in next post.

Run the program and comment below the output you are getting for a given input.

Project Euler Problem 67 Solution with Python

Maximum path sum II By starting at the top of the triangle below and moving to adjacent numbers on the row below, the maximum total from top to bottom is 23. 3 7 4 2 4 6 8 5 9 3 That is, 3 + 7 + 4 + 9 = 23. Find the maximum total from top to bottom in triangle.txt (right click and 'Save Link/Target As...'), a 15K text file containing a triangle with one-hundred rows.

Problem 43 Project Euler Solution with python

Sub-string divisibility The number, 1406357289, is a 0 to 9 pandigital number because it is made up of each of the digits 0 to 9 in some order, but it also has a rather interesting sub-string divisibility property. Let d 1 be the 1 st digit, d 2 be the 2 nd digit, and so on. In this way, we note the following: d 2 d 3 d 4 =406 is divisible by 2 d 3 d 4 d 5 =063 is divisible by 3 d 4 d 5 d 6 =635 is divisible by 5 d 5 d 6 d 7 =357 is divisible by 7 d 6 d 7 d 8 =572 is divisible by 11 d 7 d 8 d 9 =728 is divisible by 13 d 8 d 9 d 10 =289 is divisible by 17 Find the sum of all 0 to 9 pandigital numbers with this property. One might write a simple solution using direct if else statements for this problem. Using if else statements, the execution time may be a few seconds. But this is not a very good approach. I too had written a program with if else statement which will take each and every permutation of the 0-9 Pandigital and check for the conditions given in the qu...

Add/Embed SVG to Blogger website

In this post I will tell you my method(trick) of adding SVG images in a blogger website or blog. Before starting , the first thin g I am assu m ing is that you are aware of SVG if you are here. If not please see S calable V ec tor G raphics Recently when I tried to embed a SVG image for a post on pygal, I tried uploading the SVG file and blogger Image uploader came up with an error, because of which I had to find some other way.  SVG File upload Error in Blogger  I started sea rc hing Google " Embed SVG in Blogger " . I found blogorrhea , w h ich gave some i nformatio n on add ing SVG directly as a markup , which worked , but I faced another problem using this . Also th is guy has used lot of Javascript which was confusin g for me, being new to using SVG.   So I first t houg ht of learning on h ow to embed SVG in HTML and t his on e worked out. Actually we can embed SVG in HTML i n following ways: Using Object tag Using Iframe tag Using embed...
