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 55,050,331, 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 | 55,050,331 | |
| -1 | -55,050,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,050,331.
Example:
1 x 55,050,331 = 55,050,331
and
-1 x -55,050,331 = 55,050,331
Notice both answers equal 55,050,331
With that explanation out of the way, let's continue. Next, we take the number 55,050,331 and divide it by 2:
55,050,331 ÷ 2 = 27,525,165.5
If the quotient is a whole number, then 2 and 27,525,165.5 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 | 55,050,331 | |
| -1 | -55,050,331 |
Now, we try dividing 55,050,331 by 3:
55,050,331 ÷ 3 = 18,350,110.3333
If the quotient is a whole number, then 3 and 18,350,110.3333 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 | 55,050,331 | |
| -1 | -55,050,331 |
Let's try dividing by 4:
55,050,331 ÷ 4 = 13,762,582.75
If the quotient is a whole number, then 4 and 13,762,582.75 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 | 55,050,331 | |
| -1 | 55,050,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 83 | 287 | 581 | 2,311 | 3,403 | 16,177 | 23,821 | 94,751 | 191,813 | 663,257 | 1,342,691 | 7,864,333 | 55,050,331 |
| -1 | -7 | -41 | -83 | -287 | -581 | -2,311 | -3,403 | -16,177 | -23,821 | -94,751 | -191,813 | -663,257 | -1,342,691 | -7,864,333 | -55,050,331 |
