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 364,633,789, 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 | 364,633,789 | |
| -1 | -364,633,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 364,633,789.
Example:
1 x 364,633,789 = 364,633,789
and
-1 x -364,633,789 = 364,633,789
Notice both answers equal 364,633,789
With that explanation out of the way, let's continue. Next, we take the number 364,633,789 and divide it by 2:
364,633,789 ÷ 2 = 182,316,894.5
If the quotient is a whole number, then 2 and 182,316,894.5 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 | 364,633,789 | |
| -1 | -364,633,789 |
Now, we try dividing 364,633,789 by 3:
364,633,789 ÷ 3 = 121,544,596.3333
If the quotient is a whole number, then 3 and 121,544,596.3333 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 | 364,633,789 | |
| -1 | -364,633,789 |
Let's try dividing by 4:
364,633,789 ÷ 4 = 91,158,447.25
If the quotient is a whole number, then 4 and 91,158,447.25 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 | 364,633,789 | |
| -1 | 364,633,789 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 857 | 1,423 | 11,141 | 18,499 | 19,711 | 32,729 | 256,243 | 425,477 | 1,219,511 | 15,853,643 | 28,048,753 | 364,633,789 |
| -1 | -13 | -23 | -299 | -857 | -1,423 | -11,141 | -18,499 | -19,711 | -32,729 | -256,243 | -425,477 | -1,219,511 | -15,853,643 | -28,048,753 | -364,633,789 |
