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 4,411,145, 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 | 4,411,145 | |
| -1 | -4,411,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,411,145.
Example:
1 x 4,411,145 = 4,411,145
and
-1 x -4,411,145 = 4,411,145
Notice both answers equal 4,411,145
With that explanation out of the way, let's continue. Next, we take the number 4,411,145 and divide it by 2:
4,411,145 ÷ 2 = 2,205,572.5
If the quotient is a whole number, then 2 and 2,205,572.5 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 | 4,411,145 | |
| -1 | -4,411,145 |
Now, we try dividing 4,411,145 by 3:
4,411,145 ÷ 3 = 1,470,381.6667
If the quotient is a whole number, then 3 and 1,470,381.6667 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 | 4,411,145 | |
| -1 | -4,411,145 |
Let's try dividing by 4:
4,411,145 ÷ 4 = 1,102,786.25
If the quotient is a whole number, then 4 and 1,102,786.25 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 | 4,411,145 | |
| -1 | 4,411,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 149 | 155 | 191 | 745 | 955 | 4,619 | 5,921 | 23,095 | 28,459 | 29,605 | 142,295 | 882,229 | 4,411,145 |
| -1 | -5 | -31 | -149 | -155 | -191 | -745 | -955 | -4,619 | -5,921 | -23,095 | -28,459 | -29,605 | -142,295 | -882,229 | -4,411,145 |
