Count by 404 (Skip Counting by 404s)

Count by 404

Here we will show you how to count by 404, discuss counting by 404 patterns, and tell you why knowing how to count by 404 matters. To start off, note that Count by 404 means counting in 404s, or count by four hundred fours, and it is also called skip counting by 404.

How to count by 404
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 404, we count 404, 808, 1212, 1616, and so on.

In other words, to count in intervals of 404 or skip counting by 404, we start with 404 and then add 404 to get the next number, and then continue adding 404 to the previous number to keep counting by 404, like this:

404
404 + 404 = 808
808 + 404 = 1212
1212 + 404 = 1616
1616 + 404 = 2020
...

You can of course skip count by 404 forever, so it is impossible to make a list of all numbers, but below is a Count by 404 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 404, the second column has the next ten numbers you get when you skip count by 404, and so forth.

Count by 404 Patterns
We organized the Skip Counting by 404s 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 404, but don't have the Counting by 404s Chart above. Obviously, one pattern with counting by 404s is that the number increases by 404.

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 5 over and over. The pattern of the last digit when you count by 404 goes 4, 8, 2, 6, 0 and 4, 8, 2, 6, 0 and so on for as long as you count by 404.

Why Count by 404?
We think that understanding and learning about skip counting by 404 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by four hundred four, you are also creating a list of multiples of 404 that you can use in math when you need the least common multiple. 404 times n equals the nth multiple or skip count of 404.

When you skip count by 404, you are also creating a list of numbers that 404 is divisible by. On top of that, skip counting by 404 is the same as making the 404 times table.
