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 10,204,415, 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 | 10,204,415 | |
| -1 | -10,204,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,204,415.
Example:
1 x 10,204,415 = 10,204,415
and
-1 x -10,204,415 = 10,204,415
Notice both answers equal 10,204,415
With that explanation out of the way, let's continue. Next, we take the number 10,204,415 and divide it by 2:
10,204,415 ÷ 2 = 5,102,207.5
If the quotient is a whole number, then 2 and 5,102,207.5 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 | 10,204,415 | |
| -1 | -10,204,415 |
Now, we try dividing 10,204,415 by 3:
10,204,415 ÷ 3 = 3,401,471.6667
If the quotient is a whole number, then 3 and 3,401,471.6667 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 | 10,204,415 | |
| -1 | -10,204,415 |
Let's try dividing by 4:
10,204,415 ÷ 4 = 2,551,103.75
If the quotient is a whole number, then 4 and 2,551,103.75 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 | 10,204,415 | |
| -1 | 10,204,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 4,243 | 21,215 | 55,159 | 156,991 | 275,795 | 784,955 | 2,040,883 | 10,204,415 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -4,243 | -21,215 | -55,159 | -156,991 | -275,795 | -784,955 | -2,040,883 | -10,204,415 |
