Count by 813 (Skip Counting by 813s)

Count by 813

Here we will show you how to count by 813, discuss counting by 813 patterns, and tell you why knowing how to count by 813 matters. To start off, note that Count by 813 means counting in 813s, or count by eight hundred thirteens, and it is also called skip counting by 813.

How to count by 813
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 813, we count 813, 1626, 2439, 3252, and so on.

In other words, to count in intervals of 813 or skip counting by 813, we start with 813 and then add 813 to get the next number, and then continue adding 813 to the previous number to keep counting by 813, like this:

813
813 + 813 = 1626
1626 + 813 = 2439
2439 + 813 = 3252
3252 + 813 = 4065
...

You can of course skip count by 813 forever, so it is impossible to make a list of all numbers, but below is a Count by 813 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 813, the second column has the next ten numbers you get when you skip count by 813, and so forth.

Count by 813 Patterns
We organized the Skip Counting by 813s 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 813, but don't have the Counting by 813s Chart above. Obviously, one pattern with counting by 813s is that the number increases by 813.

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 813 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 813.
