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 362,084,891, 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 | 362,084,891 | |
| -1 | -362,084,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 362,084,891.
Example:
1 x 362,084,891 = 362,084,891
and
-1 x -362,084,891 = 362,084,891
Notice both answers equal 362,084,891
With that explanation out of the way, let's continue. Next, we take the number 362,084,891 and divide it by 2:
362,084,891 ÷ 2 = 181,042,445.5
If the quotient is a whole number, then 2 and 181,042,445.5 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 | 362,084,891 | |
| -1 | -362,084,891 |
Now, we try dividing 362,084,891 by 3:
362,084,891 ÷ 3 = 120,694,963.6667
If the quotient is a whole number, then 3 and 120,694,963.6667 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 | 362,084,891 | |
| -1 | -362,084,891 |
Let's try dividing by 4:
362,084,891 ÷ 4 = 90,521,222.75
If the quotient is a whole number, then 4 and 90,521,222.75 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 | 362,084,891 | |
| -1 | 362,084,891 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 167 | 511 | 1,169 | 4,243 | 12,191 | 29,701 | 85,337 | 309,739 | 708,581 | 2,168,173 | 4,960,067 | 51,726,413 | 362,084,891 |
| -1 | -7 | -73 | -167 | -511 | -1,169 | -4,243 | -12,191 | -29,701 | -85,337 | -309,739 | -708,581 | -2,168,173 | -4,960,067 | -51,726,413 | -362,084,891 |
