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 10,413,325, 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 | 10,413,325 | |
| -1 | -10,413,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,413,325.
Example:
1 x 10,413,325 = 10,413,325
and
-1 x -10,413,325 = 10,413,325
Notice both answers equal 10,413,325
With that explanation out of the way, let's continue. Next, we take the number 10,413,325 and divide it by 2:
10,413,325 ÷ 2 = 5,206,662.5
If the quotient is a whole number, then 2 and 5,206,662.5 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 | 10,413,325 | |
| -1 | -10,413,325 |
Now, we try dividing 10,413,325 by 3:
10,413,325 ÷ 3 = 3,471,108.3333
If the quotient is a whole number, then 3 and 3,471,108.3333 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 | 10,413,325 | |
| -1 | -10,413,325 |
Let's try dividing by 4:
10,413,325 ÷ 4 = 2,603,331.25
If the quotient is a whole number, then 4 and 2,603,331.25 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 | 10,413,325 | |
| -1 | 10,413,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 179 | 325 | 895 | 2,327 | 4,475 | 11,635 | 32,041 | 58,175 | 160,205 | 416,533 | 801,025 | 2,082,665 | 10,413,325 |
| -1 | -5 | -13 | -25 | -65 | -179 | -325 | -895 | -2,327 | -4,475 | -11,635 | -32,041 | -58,175 | -160,205 | -416,533 | -801,025 | -2,082,665 | -10,413,325 |
