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 2,240,095, 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 | 2,240,095 | |
| -1 | -2,240,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,240,095.
Example:
1 x 2,240,095 = 2,240,095
and
-1 x -2,240,095 = 2,240,095
Notice both answers equal 2,240,095
With that explanation out of the way, let's continue. Next, we take the number 2,240,095 and divide it by 2:
2,240,095 ÷ 2 = 1,120,047.5
If the quotient is a whole number, then 2 and 1,120,047.5 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 | 2,240,095 | |
| -1 | -2,240,095 |
Now, we try dividing 2,240,095 by 3:
2,240,095 ÷ 3 = 746,698.3333
If the quotient is a whole number, then 3 and 746,698.3333 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 | 2,240,095 | |
| -1 | -2,240,095 |
Let's try dividing by 4:
2,240,095 ÷ 4 = 560,023.75
If the quotient is a whole number, then 4 and 560,023.75 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 | 2,240,095 | |
| -1 | 2,240,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 169 | 241 | 715 | 845 | 1,205 | 1,859 | 2,651 | 3,133 | 9,295 | 13,255 | 15,665 | 34,463 | 40,729 | 172,315 | 203,645 | 448,019 | 2,240,095 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -169 | -241 | -715 | -845 | -1,205 | -1,859 | -2,651 | -3,133 | -9,295 | -13,255 | -15,665 | -34,463 | -40,729 | -172,315 | -203,645 | -448,019 | -2,240,095 |
