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 9,729,545, 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 | 9,729,545 | |
| -1 | -9,729,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,729,545.
Example:
1 x 9,729,545 = 9,729,545
and
-1 x -9,729,545 = 9,729,545
Notice both answers equal 9,729,545
With that explanation out of the way, let's continue. Next, we take the number 9,729,545 and divide it by 2:
9,729,545 ÷ 2 = 4,864,772.5
If the quotient is a whole number, then 2 and 4,864,772.5 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 | 9,729,545 | |
| -1 | -9,729,545 |
Now, we try dividing 9,729,545 by 3:
9,729,545 ÷ 3 = 3,243,181.6667
If the quotient is a whole number, then 3 and 3,243,181.6667 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 | 9,729,545 | |
| -1 | -9,729,545 |
Let's try dividing by 4:
9,729,545 ÷ 4 = 2,432,386.25
If the quotient is a whole number, then 4 and 2,432,386.25 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 | 9,729,545 | |
| -1 | 9,729,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 179 | 895 | 1,253 | 1,553 | 6,265 | 7,765 | 10,871 | 54,355 | 277,987 | 1,389,935 | 1,945,909 | 9,729,545 |
| -1 | -5 | -7 | -35 | -179 | -895 | -1,253 | -1,553 | -6,265 | -7,765 | -10,871 | -54,355 | -277,987 | -1,389,935 | -1,945,909 | -9,729,545 |
