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 2,240,407, 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 | 2,240,407 | |
| -1 | -2,240,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,240,407.
Example:
1 x 2,240,407 = 2,240,407
and
-1 x -2,240,407 = 2,240,407
Notice both answers equal 2,240,407
With that explanation out of the way, let's continue. Next, we take the number 2,240,407 and divide it by 2:
2,240,407 ÷ 2 = 1,120,203.5
If the quotient is a whole number, then 2 and 1,120,203.5 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 | 2,240,407 | |
| -1 | -2,240,407 |
Now, we try dividing 2,240,407 by 3:
2,240,407 ÷ 3 = 746,802.3333
If the quotient is a whole number, then 3 and 746,802.3333 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 | 2,240,407 | |
| -1 | -2,240,407 |
Let's try dividing by 4:
2,240,407 ÷ 4 = 560,101.75
If the quotient is a whole number, then 4 and 560,101.75 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 | 2,240,407 | |
| -1 | 2,240,407 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 59 | 127 | 299 | 767 | 1,357 | 1,651 | 2,921 | 7,493 | 17,641 | 37,973 | 97,409 | 172,339 | 2,240,407 |
| -1 | -13 | -23 | -59 | -127 | -299 | -767 | -1,357 | -1,651 | -2,921 | -7,493 | -17,641 | -37,973 | -97,409 | -172,339 | -2,240,407 |
