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 363,132,445, 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 | 363,132,445 | |
| -1 | -363,132,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 363,132,445.
Example:
1 x 363,132,445 = 363,132,445
and
-1 x -363,132,445 = 363,132,445
Notice both answers equal 363,132,445
With that explanation out of the way, let's continue. Next, we take the number 363,132,445 and divide it by 2:
363,132,445 ÷ 2 = 181,566,222.5
If the quotient is a whole number, then 2 and 181,566,222.5 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 | 363,132,445 | |
| -1 | -363,132,445 |
Now, we try dividing 363,132,445 by 3:
363,132,445 ÷ 3 = 121,044,148.3333
If the quotient is a whole number, then 3 and 121,044,148.3333 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 | 363,132,445 | |
| -1 | -363,132,445 |
Let's try dividing by 4:
363,132,445 ÷ 4 = 90,783,111.25
If the quotient is a whole number, then 4 and 90,783,111.25 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 | 363,132,445 | |
| -1 | 363,132,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 593 | 2,965 | 7,709 | 9,421 | 38,545 | 47,105 | 122,473 | 612,365 | 5,586,653 | 27,933,265 | 72,626,489 | 363,132,445 |
| -1 | -5 | -13 | -65 | -593 | -2,965 | -7,709 | -9,421 | -38,545 | -47,105 | -122,473 | -612,365 | -5,586,653 | -27,933,265 | -72,626,489 | -363,132,445 |
