Count by 339 (Skip Counting by 339s)

Count by 339

Here we will show you how to count by 339, discuss counting by 339 patterns, and tell you why knowing how to count by 339 matters. To start off, note that Count by 339 means counting in 339s, or count by three hundred thirty-nines, and it is also called skip counting by 339.

How to count by 339
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 339, we count 339, 678, 1017, 1356, and so on.

In other words, to count in intervals of 339 or skip counting by 339, we start with 339 and then add 339 to get the next number, and then continue adding 339 to the previous number to keep counting by 339, like this:

339
339 + 339 = 678
678 + 339 = 1017
1017 + 339 = 1356
1356 + 339 = 1695
...

You can of course skip count by 339 forever, so it is impossible to make a list of all numbers, but below is a Count by 339 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 339, the second column has the next ten numbers you get when you skip count by 339, and so forth.

Count by 339 Patterns
We organized the Skip Counting by 339s 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 339, but don't have the Counting by 339s Chart above. Obviously, one pattern with counting by 339s is that the number increases by 339.

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 339 goes 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and so on for as long as you count by 339.

Why Count by 339?
We think that understanding and learning about skip counting by 339 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by three hundred thirty-nine, you are also creating a list of multiples of 339 that you can use in math when you need the least common multiple. 339 times n equals the nth multiple or skip count of 339.

When you skip count by 339, you are also creating a list of numbers that 339 is divisible by. On top of that, skip counting by 339 is the same as making the 339 times table.
