Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 10,879,561, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 10,879,561 | |
| -1 | -10,879,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,879,561.
Example:
1 x 10,879,561 = 10,879,561
and
-1 x -10,879,561 = 10,879,561
Notice both answers equal 10,879,561
With that explanation out of the way, let's continue. Next, we take the number 10,879,561 and divide it by 2:
10,879,561 ÷ 2 = 5,439,780.5
If the quotient is a whole number, then 2 and 5,439,780.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 10,879,561 | |
| -1 | -10,879,561 |
Now, we try dividing 10,879,561 by 3:
10,879,561 ÷ 3 = 3,626,520.3333
If the quotient is a whole number, then 3 and 3,626,520.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 10,879,561 | |
| -1 | -10,879,561 |
Let's try dividing by 4:
10,879,561 ÷ 4 = 2,719,890.25
If the quotient is a whole number, then 4 and 2,719,890.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 10,879,561 | |
| -1 | 10,879,561 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 229 | 617 | 1,603 | 2,519 | 4,319 | 6,787 | 17,633 | 47,509 | 141,293 | 989,051 | 1,554,223 | 10,879,561 |
| -1 | -7 | -11 | -77 | -229 | -617 | -1,603 | -2,519 | -4,319 | -6,787 | -17,633 | -47,509 | -141,293 | -989,051 | -1,554,223 | -10,879,561 |
