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 4,377,581, 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 | 4,377,581 | |
| -1 | -4,377,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,377,581.
Example:
1 x 4,377,581 = 4,377,581
and
-1 x -4,377,581 = 4,377,581
Notice both answers equal 4,377,581
With that explanation out of the way, let's continue. Next, we take the number 4,377,581 and divide it by 2:
4,377,581 ÷ 2 = 2,188,790.5
If the quotient is a whole number, then 2 and 2,188,790.5 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 | 4,377,581 | |
| -1 | -4,377,581 |
Now, we try dividing 4,377,581 by 3:
4,377,581 ÷ 3 = 1,459,193.6667
If the quotient is a whole number, then 3 and 1,459,193.6667 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 | 4,377,581 | |
| -1 | -4,377,581 |
Let's try dividing by 4:
4,377,581 ÷ 4 = 1,094,395.25
If the quotient is a whole number, then 4 and 1,094,395.25 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 | 4,377,581 | |
| -1 | 4,377,581 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 479 | 481 | 703 | 6,227 | 9,101 | 9,139 | 17,723 | 118,313 | 230,399 | 336,737 | 4,377,581 |
| -1 | -13 | -19 | -37 | -247 | -479 | -481 | -703 | -6,227 | -9,101 | -9,139 | -17,723 | -118,313 | -230,399 | -336,737 | -4,377,581 |
