Count by 2403 (Skip Counting by 2403s)

Count by 2403

Here we will show you how to count by 2403, discuss counting by 2403 patterns, and tell you why knowing how to count by 2403 matters. To start off, note that Count by 2403 means counting in 2403s, or count by two thousand four hundred threes, and it is also called skip counting by 2403.

How to count by 2403
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 2403, we count 2403, 4806, 7209, 9612, and so on.

In other words, to count in intervals of 2403 or skip counting by 2403, we start with 2403 and then add 2403 to get the next number, and then continue adding 2403 to the previous number to keep counting by 2403, like this:

2403
2403 + 2403 = 4806
4806 + 2403 = 7209
7209 + 2403 = 9612
9612 + 2403 = 12015
...

You can of course skip count by 2403 forever, so it is impossible to make a list of all numbers, but below is a Count by 2403 Chart of the first 100 numbers to get you started.

Looking at the chart above, you will see that the first column has the first ten numbers you get when you skip count by 2403, the second column has the next ten numbers you get when you skip count by 2403, and so forth.

Count by 2403 Patterns
We organized the Skip Counting by 2403s Chart above in 10 rows and 10 columns so you can easily identify patterns.

Skip counting always creates patterns. Figuring out these patterns may help you if want to count by 2403, but don't have the Counting by 2403s Chart above. Obviously, one pattern with counting by 2403s is that the number increases by 2403.

Furthermore, if you look at each row above, each number in the row has the same last digit (ones place). That means that every tenth number has the same last digit.

If you look down the columns, you will see that the last digit (ones place) repeats itself in blocks of 10 over and over. The pattern of the last digit when you count by 2403 goes 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and so on for as long as you count by 2403.

When you count by two thousand four hundred three, you are also creating a list of multiples of 2403 that you can use in math when you need the least common multiple. 2403 times n equals the nth multiple or skip count of 2403.
