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 9,823,645, 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 | 9,823,645 | |
| -1 | -9,823,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,823,645.
Example:
1 x 9,823,645 = 9,823,645
and
-1 x -9,823,645 = 9,823,645
Notice both answers equal 9,823,645
With that explanation out of the way, let's continue. Next, we take the number 9,823,645 and divide it by 2:
9,823,645 ÷ 2 = 4,911,822.5
If the quotient is a whole number, then 2 and 4,911,822.5 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 | 9,823,645 | |
| -1 | -9,823,645 |
Now, we try dividing 9,823,645 by 3:
9,823,645 ÷ 3 = 3,274,548.3333
If the quotient is a whole number, then 3 and 3,274,548.3333 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 | 9,823,645 | |
| -1 | -9,823,645 |
Let's try dividing by 4:
9,823,645 ÷ 4 = 2,455,911.25
If the quotient is a whole number, then 4 and 2,455,911.25 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 | 9,823,645 | |
| -1 | 9,823,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 6,571 | 32,855 | 85,423 | 151,133 | 427,115 | 755,665 | 1,964,729 | 9,823,645 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -6,571 | -32,855 | -85,423 | -151,133 | -427,115 | -755,665 | -1,964,729 | -9,823,645 |
