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 5,547,031, 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 | 5,547,031 | |
| -1 | -5,547,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,547,031.
Example:
1 x 5,547,031 = 5,547,031
and
-1 x -5,547,031 = 5,547,031
Notice both answers equal 5,547,031
With that explanation out of the way, let's continue. Next, we take the number 5,547,031 and divide it by 2:
5,547,031 ÷ 2 = 2,773,515.5
If the quotient is a whole number, then 2 and 2,773,515.5 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 | 5,547,031 | |
| -1 | -5,547,031 |
Now, we try dividing 5,547,031 by 3:
5,547,031 ÷ 3 = 1,849,010.3333
If the quotient is a whole number, then 3 and 1,849,010.3333 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 | 5,547,031 | |
| -1 | -5,547,031 |
Let's try dividing by 4:
5,547,031 ÷ 4 = 1,386,757.75
If the quotient is a whole number, then 4 and 1,386,757.75 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 | 5,547,031 | |
| -1 | 5,547,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 179 | 233 | 1,253 | 1,631 | 3,401 | 4,427 | 23,807 | 30,989 | 41,707 | 291,949 | 792,433 | 5,547,031 |
| -1 | -7 | -19 | -133 | -179 | -233 | -1,253 | -1,631 | -3,401 | -4,427 | -23,807 | -30,989 | -41,707 | -291,949 | -792,433 | -5,547,031 |
