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 2,240,575, 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 | 2,240,575 | |
| -1 | -2,240,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,240,575.
Example:
1 x 2,240,575 = 2,240,575
and
-1 x -2,240,575 = 2,240,575
Notice both answers equal 2,240,575
With that explanation out of the way, let's continue. Next, we take the number 2,240,575 and divide it by 2:
2,240,575 ÷ 2 = 1,120,287.5
If the quotient is a whole number, then 2 and 1,120,287.5 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 | 2,240,575 | |
| -1 | -2,240,575 |
Now, we try dividing 2,240,575 by 3:
2,240,575 ÷ 3 = 746,858.3333
If the quotient is a whole number, then 3 and 746,858.3333 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 | 2,240,575 | |
| -1 | -2,240,575 |
Let's try dividing by 4:
2,240,575 ÷ 4 = 560,143.75
If the quotient is a whole number, then 4 and 560,143.75 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 | 2,240,575 | |
| -1 | 2,240,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 53 | 89 | 95 | 265 | 445 | 475 | 1,007 | 1,325 | 1,691 | 2,225 | 4,717 | 5,035 | 8,455 | 23,585 | 25,175 | 42,275 | 89,623 | 117,925 | 448,115 | 2,240,575 |
| -1 | -5 | -19 | -25 | -53 | -89 | -95 | -265 | -445 | -475 | -1,007 | -1,325 | -1,691 | -2,225 | -4,717 | -5,035 | -8,455 | -23,585 | -25,175 | -42,275 | -89,623 | -117,925 | -448,115 | -2,240,575 |
