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 361,263,305, 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 | 361,263,305 | |
| -1 | -361,263,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,263,305.
Example:
1 x 361,263,305 = 361,263,305
and
-1 x -361,263,305 = 361,263,305
Notice both answers equal 361,263,305
With that explanation out of the way, let's continue. Next, we take the number 361,263,305 and divide it by 2:
361,263,305 ÷ 2 = 180,631,652.5
If the quotient is a whole number, then 2 and 180,631,652.5 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 | 361,263,305 | |
| -1 | -361,263,305 |
Now, we try dividing 361,263,305 by 3:
361,263,305 ÷ 3 = 120,421,101.6667
If the quotient is a whole number, then 3 and 120,421,101.6667 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 | 361,263,305 | |
| -1 | -361,263,305 |
Let's try dividing by 4:
361,263,305 ÷ 4 = 90,315,826.25
If the quotient is a whole number, then 4 and 90,315,826.25 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 | 361,263,305 | |
| -1 | 361,263,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 179,287 | 896,435 | 2,330,731 | 5,557,897 | 11,653,655 | 27,789,485 | 72,252,661 | 361,263,305 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -179,287 | -896,435 | -2,330,731 | -5,557,897 | -11,653,655 | -27,789,485 | -72,252,661 | -361,263,305 |
