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 10,112,165, 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 | 10,112,165 | |
| -1 | -10,112,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,112,165.
Example:
1 x 10,112,165 = 10,112,165
and
-1 x -10,112,165 = 10,112,165
Notice both answers equal 10,112,165
With that explanation out of the way, let's continue. Next, we take the number 10,112,165 and divide it by 2:
10,112,165 ÷ 2 = 5,056,082.5
If the quotient is a whole number, then 2 and 5,056,082.5 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 | 10,112,165 | |
| -1 | -10,112,165 |
Now, we try dividing 10,112,165 by 3:
10,112,165 ÷ 3 = 3,370,721.6667
If the quotient is a whole number, then 3 and 3,370,721.6667 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 | 10,112,165 | |
| -1 | -10,112,165 |
Let's try dividing by 4:
10,112,165 ÷ 4 = 2,528,041.25
If the quotient is a whole number, then 4 and 2,528,041.25 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 | 10,112,165 | |
| -1 | 10,112,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 311 | 929 | 1,555 | 2,177 | 4,645 | 6,503 | 10,885 | 32,515 | 288,919 | 1,444,595 | 2,022,433 | 10,112,165 |
| -1 | -5 | -7 | -35 | -311 | -929 | -1,555 | -2,177 | -4,645 | -6,503 | -10,885 | -32,515 | -288,919 | -1,444,595 | -2,022,433 | -10,112,165 |
