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 2,248,399, 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 | 2,248,399 | |
| -1 | -2,248,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,248,399.
Example:
1 x 2,248,399 = 2,248,399
and
-1 x -2,248,399 = 2,248,399
Notice both answers equal 2,248,399
With that explanation out of the way, let's continue. Next, we take the number 2,248,399 and divide it by 2:
2,248,399 ÷ 2 = 1,124,199.5
If the quotient is a whole number, then 2 and 1,124,199.5 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 | 2,248,399 | |
| -1 | -2,248,399 |
Now, we try dividing 2,248,399 by 3:
2,248,399 ÷ 3 = 749,466.3333
If the quotient is a whole number, then 3 and 749,466.3333 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 | 2,248,399 | |
| -1 | -2,248,399 |
Let's try dividing by 4:
2,248,399 ÷ 4 = 562,099.75
If the quotient is a whole number, then 4 and 562,099.75 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 | 2,248,399 | |
| -1 | 2,248,399 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 41 | 61 | 899 | 1,189 | 1,271 | 1,769 | 1,891 | 2,501 | 36,859 | 54,839 | 72,529 | 77,531 | 2,248,399 |
| -1 | -29 | -31 | -41 | -61 | -899 | -1,189 | -1,271 | -1,769 | -1,891 | -2,501 | -36,859 | -54,839 | -72,529 | -77,531 | -2,248,399 |
