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 360,398,105, 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 | 360,398,105 | |
| -1 | -360,398,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,398,105.
Example:
1 x 360,398,105 = 360,398,105
and
-1 x -360,398,105 = 360,398,105
Notice both answers equal 360,398,105
With that explanation out of the way, let's continue. Next, we take the number 360,398,105 and divide it by 2:
360,398,105 ÷ 2 = 180,199,052.5
If the quotient is a whole number, then 2 and 180,199,052.5 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 | 360,398,105 | |
| -1 | -360,398,105 |
Now, we try dividing 360,398,105 by 3:
360,398,105 ÷ 3 = 120,132,701.6667
If the quotient is a whole number, then 3 and 120,132,701.6667 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 | 360,398,105 | |
| -1 | -360,398,105 |
Let's try dividing by 4:
360,398,105 ÷ 4 = 90,099,526.25
If the quotient is a whole number, then 4 and 90,099,526.25 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 | 360,398,105 | |
| -1 | 360,398,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 223 | 263 | 1,115 | 1,229 | 1,315 | 6,145 | 58,649 | 274,067 | 293,245 | 323,227 | 1,370,335 | 1,616,135 | 72,079,621 | 360,398,105 |
| -1 | -5 | -223 | -263 | -1,115 | -1,229 | -1,315 | -6,145 | -58,649 | -274,067 | -293,245 | -323,227 | -1,370,335 | -1,616,135 | -72,079,621 | -360,398,105 |
