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 10,057,115, 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 | 10,057,115 | |
| -1 | -10,057,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,057,115.
Example:
1 x 10,057,115 = 10,057,115
and
-1 x -10,057,115 = 10,057,115
Notice both answers equal 10,057,115
With that explanation out of the way, let's continue. Next, we take the number 10,057,115 and divide it by 2:
10,057,115 ÷ 2 = 5,028,557.5
If the quotient is a whole number, then 2 and 5,028,557.5 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 | 10,057,115 | |
| -1 | -10,057,115 |
Now, we try dividing 10,057,115 by 3:
10,057,115 ÷ 3 = 3,352,371.6667
If the quotient is a whole number, then 3 and 3,352,371.6667 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 | 10,057,115 | |
| -1 | -10,057,115 |
Let's try dividing by 4:
10,057,115 ÷ 4 = 2,514,278.75
If the quotient is a whole number, then 4 and 2,514,278.75 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 | 10,057,115 | |
| -1 | 10,057,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 179 | 661 | 895 | 3,043 | 3,305 | 11,237 | 15,215 | 56,185 | 118,319 | 591,595 | 2,011,423 | 10,057,115 |
| -1 | -5 | -17 | -85 | -179 | -661 | -895 | -3,043 | -3,305 | -11,237 | -15,215 | -56,185 | -118,319 | -591,595 | -2,011,423 | -10,057,115 |
