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 361,442,339, 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 | 361,442,339 | |
| -1 | -361,442,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,442,339.
Example:
1 x 361,442,339 = 361,442,339
and
-1 x -361,442,339 = 361,442,339
Notice both answers equal 361,442,339
With that explanation out of the way, let's continue. Next, we take the number 361,442,339 and divide it by 2:
361,442,339 ÷ 2 = 180,721,169.5
If the quotient is a whole number, then 2 and 180,721,169.5 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 | 361,442,339 | |
| -1 | -361,442,339 |
Now, we try dividing 361,442,339 by 3:
361,442,339 ÷ 3 = 120,480,779.6667
If the quotient is a whole number, then 3 and 120,480,779.6667 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 | 361,442,339 | |
| -1 | -361,442,339 |
Let's try dividing by 4:
361,442,339 ÷ 4 = 90,360,584.75
If the quotient is a whole number, then 4 and 90,360,584.75 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 | 361,442,339 | |
| -1 | 361,442,339 |
If you did it right, you will end up with this table:
| 1 | 19 | 181 | 227 | 463 | 3,439 | 4,313 | 8,797 | 41,087 | 83,803 | 105,101 | 780,653 | 1,592,257 | 1,996,919 | 19,023,281 | 361,442,339 |
| -1 | -19 | -181 | -227 | -463 | -3,439 | -4,313 | -8,797 | -41,087 | -83,803 | -105,101 | -780,653 | -1,592,257 | -1,996,919 | -19,023,281 | -361,442,339 |
