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 223,032,115, 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 | 223,032,115 | |
| -1 | -223,032,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,032,115.
Example:
1 x 223,032,115 = 223,032,115
and
-1 x -223,032,115 = 223,032,115
Notice both answers equal 223,032,115
With that explanation out of the way, let's continue. Next, we take the number 223,032,115 and divide it by 2:
223,032,115 ÷ 2 = 111,516,057.5
If the quotient is a whole number, then 2 and 111,516,057.5 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 | 223,032,115 | |
| -1 | -223,032,115 |
Now, we try dividing 223,032,115 by 3:
223,032,115 ÷ 3 = 74,344,038.3333
If the quotient is a whole number, then 3 and 74,344,038.3333 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 | 223,032,115 | |
| -1 | -223,032,115 |
Let's try dividing by 4:
223,032,115 ÷ 4 = 55,758,028.75
If the quotient is a whole number, then 4 and 55,758,028.75 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 | 223,032,115 | |
| -1 | 223,032,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 1,093 | 1,103 | 5,465 | 5,515 | 40,441 | 40,811 | 202,205 | 204,055 | 1,205,579 | 6,027,895 | 44,606,423 | 223,032,115 |
| -1 | -5 | -37 | -185 | -1,093 | -1,103 | -5,465 | -5,515 | -40,441 | -40,811 | -202,205 | -204,055 | -1,205,579 | -6,027,895 | -44,606,423 | -223,032,115 |
