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 364,045,015, 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 | 364,045,015 | |
| -1 | -364,045,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 364,045,015.
Example:
1 x 364,045,015 = 364,045,015
and
-1 x -364,045,015 = 364,045,015
Notice both answers equal 364,045,015
With that explanation out of the way, let's continue. Next, we take the number 364,045,015 and divide it by 2:
364,045,015 ÷ 2 = 182,022,507.5
If the quotient is a whole number, then 2 and 182,022,507.5 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 | 364,045,015 | |
| -1 | -364,045,015 |
Now, we try dividing 364,045,015 by 3:
364,045,015 ÷ 3 = 121,348,338.3333
If the quotient is a whole number, then 3 and 121,348,338.3333 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 | 364,045,015 | |
| -1 | -364,045,015 |
Let's try dividing by 4:
364,045,015 ÷ 4 = 91,011,253.75
If the quotient is a whole number, then 4 and 91,011,253.75 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 | 364,045,015 | |
| -1 | 364,045,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 163 | 421 | 815 | 1,061 | 2,105 | 5,305 | 68,623 | 172,943 | 343,115 | 446,681 | 864,715 | 2,233,405 | 72,809,003 | 364,045,015 |
| -1 | -5 | -163 | -421 | -815 | -1,061 | -2,105 | -5,305 | -68,623 | -172,943 | -343,115 | -446,681 | -864,715 | -2,233,405 | -72,809,003 | -364,045,015 |
