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 10,666,145, 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 | 10,666,145 | |
| -1 | -10,666,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,666,145.
Example:
1 x 10,666,145 = 10,666,145
and
-1 x -10,666,145 = 10,666,145
Notice both answers equal 10,666,145
With that explanation out of the way, let's continue. Next, we take the number 10,666,145 and divide it by 2:
10,666,145 ÷ 2 = 5,333,072.5
If the quotient is a whole number, then 2 and 5,333,072.5 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 | 10,666,145 | |
| -1 | -10,666,145 |
Now, we try dividing 10,666,145 by 3:
10,666,145 ÷ 3 = 3,555,381.6667
If the quotient is a whole number, then 3 and 3,555,381.6667 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 | 10,666,145 | |
| -1 | -10,666,145 |
Let's try dividing by 4:
10,666,145 ÷ 4 = 2,666,536.25
If the quotient is a whole number, then 4 and 2,666,536.25 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 | 10,666,145 | |
| -1 | 10,666,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 193 | 965 | 1,351 | 1,579 | 6,755 | 7,895 | 11,053 | 55,265 | 304,747 | 1,523,735 | 2,133,229 | 10,666,145 |
| -1 | -5 | -7 | -35 | -193 | -965 | -1,351 | -1,579 | -6,755 | -7,895 | -11,053 | -55,265 | -304,747 | -1,523,735 | -2,133,229 | -10,666,145 |
