Welcome to our multiples category. A multiple b of a natural number a is a whole positive number which contains a n times. In other words b = n × a; n is called multiplier or coefficient. In our posts we give you the first 101 multiples for a = 1 up to a = 1000. We then go on to discuss the submultiples of the number a starting with the definition, introducing our calculator, and finally answering the frequently asked questions in the context. Of course, we also show you a method to test whether a given number is a (sub)multiple of another number. At the end of each article you have the opportunity to ask a question, or to leave a comment. This category contains 1000 entries at the time of this writing. Therefore, you may want to consider using our search form instead of navigating through so many category pages.
