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 364,085,891, 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 | 364,085,891 | |
| -1 | -364,085,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 364,085,891.
Example:
1 x 364,085,891 = 364,085,891
and
-1 x -364,085,891 = 364,085,891
Notice both answers equal 364,085,891
With that explanation out of the way, let's continue. Next, we take the number 364,085,891 and divide it by 2:
364,085,891 ÷ 2 = 182,042,945.5
If the quotient is a whole number, then 2 and 182,042,945.5 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 | 364,085,891 | |
| -1 | -364,085,891 |
Now, we try dividing 364,085,891 by 3:
364,085,891 ÷ 3 = 121,361,963.6667
If the quotient is a whole number, then 3 and 121,361,963.6667 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 | 364,085,891 | |
| -1 | -364,085,891 |
Let's try dividing by 4:
364,085,891 ÷ 4 = 91,021,472.75
If the quotient is a whole number, then 4 and 91,021,472.75 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 | 364,085,891 | |
| -1 | 364,085,891 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 263 | 1,079 | 1,283 | 3,419 | 16,679 | 21,829 | 106,489 | 283,777 | 337,429 | 1,384,357 | 4,386,577 | 28,006,607 | 364,085,891 |
| -1 | -13 | -83 | -263 | -1,079 | -1,283 | -3,419 | -16,679 | -21,829 | -106,489 | -283,777 | -337,429 | -1,384,357 | -4,386,577 | -28,006,607 | -364,085,891 |
