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 366,613,645, 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 | 366,613,645 | |
| -1 | -366,613,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 366,613,645.
Example:
1 x 366,613,645 = 366,613,645
and
-1 x -366,613,645 = 366,613,645
Notice both answers equal 366,613,645
With that explanation out of the way, let's continue. Next, we take the number 366,613,645 and divide it by 2:
366,613,645 ÷ 2 = 183,306,822.5
If the quotient is a whole number, then 2 and 183,306,822.5 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 | 366,613,645 | |
| -1 | -366,613,645 |
Now, we try dividing 366,613,645 by 3:
366,613,645 ÷ 3 = 122,204,548.3333
If the quotient is a whole number, then 3 and 122,204,548.3333 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 | 366,613,645 | |
| -1 | -366,613,645 |
Let's try dividing by 4:
366,613,645 ÷ 4 = 91,653,411.25
If the quotient is a whole number, then 4 and 91,653,411.25 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 | 366,613,645 | |
| -1 | 366,613,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,153 | 3,347 | 5,765 | 16,735 | 21,907 | 63,593 | 109,535 | 317,965 | 3,859,091 | 19,295,455 | 73,322,729 | 366,613,645 |
| -1 | -5 | -19 | -95 | -1,153 | -3,347 | -5,765 | -16,735 | -21,907 | -63,593 | -109,535 | -317,965 | -3,859,091 | -19,295,455 | -73,322,729 | -366,613,645 |
