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 9,873,745, 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 | 9,873,745 | |
| -1 | -9,873,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,873,745.
Example:
1 x 9,873,745 = 9,873,745
and
-1 x -9,873,745 = 9,873,745
Notice both answers equal 9,873,745
With that explanation out of the way, let's continue. Next, we take the number 9,873,745 and divide it by 2:
9,873,745 ÷ 2 = 4,936,872.5
If the quotient is a whole number, then 2 and 4,936,872.5 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 | 9,873,745 | |
| -1 | -9,873,745 |
Now, we try dividing 9,873,745 by 3:
9,873,745 ÷ 3 = 3,291,248.3333
If the quotient is a whole number, then 3 and 3,291,248.3333 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 | 9,873,745 | |
| -1 | -9,873,745 |
Let's try dividing by 4:
9,873,745 ÷ 4 = 2,468,436.25
If the quotient is a whole number, then 4 and 2,468,436.25 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 | 9,873,745 | |
| -1 | 9,873,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 191 | 211 | 245 | 955 | 1,055 | 1,337 | 1,477 | 6,685 | 7,385 | 9,359 | 10,339 | 40,301 | 46,795 | 51,695 | 201,505 | 282,107 | 1,410,535 | 1,974,749 | 9,873,745 |
| -1 | -5 | -7 | -35 | -49 | -191 | -211 | -245 | -955 | -1,055 | -1,337 | -1,477 | -6,685 | -7,385 | -9,359 | -10,339 | -40,301 | -46,795 | -51,695 | -201,505 | -282,107 | -1,410,535 | -1,974,749 | -9,873,745 |
