Count by 861 (Skip Counting by 861s)

Count by 861

Here we will show you how to count by 861, discuss counting by 861 patterns, and tell you why knowing how to count by 861 matters. To start off, note that Count by 861 means counting in 861s, or count by eight hundred sixty-ones, and it is also called skip counting by 861.

How to count by 861
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 861, we count 861, 1722, 2583, 3444, and so on.

In other words, to count in intervals of 861 or skip counting by 861, we start with 861 and then add 861 to get the next number, and then continue adding 861 to the previous number to keep counting by 861, like this:

861
861 + 861 = 1722
1722 + 861 = 2583
2583 + 861 = 3444
3444 + 861 = 4305
...

You can of course skip count by 861 forever, so it is impossible to make a list of all numbers, but below is a Count by 861 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 861, the second column has the next ten numbers you get when you skip count by 861, and so forth.

Count by 861 Patterns
We organized the Skip Counting by 861s 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 861, but don't have the Counting by 861s Chart above. Obviously, one pattern with counting by 861s is that the number increases by 861.

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 861 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 861.

Why Count by 861?
We think that understanding and learning about skip counting by 861 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by eight hundred sixty-one, you are also creating a list of multiples of 861 that you can use in math when you need the least common multiple. 861 times n equals the nth multiple or skip count of 861.

When you skip count by 861, you are also creating a list of numbers that 861 is divisible by. On top of that, skip counting by 861 is the same as making the 861 times table.
