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 404,135,155, 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 | 404,135,155 | |
| -1 | -404,135,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,135,155.
Example:
1 x 404,135,155 = 404,135,155
and
-1 x -404,135,155 = 404,135,155
Notice both answers equal 404,135,155
With that explanation out of the way, let's continue. Next, we take the number 404,135,155 and divide it by 2:
404,135,155 ÷ 2 = 202,067,577.5
If the quotient is a whole number, then 2 and 202,067,577.5 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 | 404,135,155 | |
| -1 | -404,135,155 |
Now, we try dividing 404,135,155 by 3:
404,135,155 ÷ 3 = 134,711,718.3333
If the quotient is a whole number, then 3 and 134,711,718.3333 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 | 404,135,155 | |
| -1 | -404,135,155 |
Let's try dividing by 4:
404,135,155 ÷ 4 = 101,033,788.75
If the quotient is a whole number, then 4 and 101,033,788.75 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 | 404,135,155 | |
| -1 | 404,135,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 205 | 1,189 | 5,945 | 67,979 | 339,895 | 1,971,391 | 2,787,139 | 9,856,955 | 13,935,695 | 80,827,031 | 404,135,155 |
| -1 | -5 | -29 | -41 | -145 | -205 | -1,189 | -5,945 | -67,979 | -339,895 | -1,971,391 | -2,787,139 | -9,856,955 | -13,935,695 | -80,827,031 | -404,135,155 |
