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 9,861,319, 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 | 9,861,319 | |
| -1 | -9,861,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,861,319.
Example:
1 x 9,861,319 = 9,861,319
and
-1 x -9,861,319 = 9,861,319
Notice both answers equal 9,861,319
With that explanation out of the way, let's continue. Next, we take the number 9,861,319 and divide it by 2:
9,861,319 ÷ 2 = 4,930,659.5
If the quotient is a whole number, then 2 and 4,930,659.5 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 | 9,861,319 | |
| -1 | -9,861,319 |
Now, we try dividing 9,861,319 by 3:
9,861,319 ÷ 3 = 3,287,106.3333
If the quotient is a whole number, then 3 and 3,287,106.3333 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 | 9,861,319 | |
| -1 | -9,861,319 |
Let's try dividing by 4:
9,861,319 ÷ 4 = 2,465,329.75
If the quotient is a whole number, then 4 and 2,465,329.75 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 | 9,861,319 | |
| -1 | 9,861,319 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 59 | 169 | 299 | 559 | 767 | 989 | 1,357 | 2,537 | 3,887 | 7,267 | 9,971 | 12,857 | 17,641 | 32,981 | 58,351 | 167,141 | 229,333 | 428,753 | 758,563 | 9,861,319 |
| -1 | -13 | -23 | -43 | -59 | -169 | -299 | -559 | -767 | -989 | -1,357 | -2,537 | -3,887 | -7,267 | -9,971 | -12,857 | -17,641 | -32,981 | -58,351 | -167,141 | -229,333 | -428,753 | -758,563 | -9,861,319 |
