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 412,553,155, 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 | 412,553,155 | |
| -1 | -412,553,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 412,553,155.
Example:
1 x 412,553,155 = 412,553,155
and
-1 x -412,553,155 = 412,553,155
Notice both answers equal 412,553,155
With that explanation out of the way, let's continue. Next, we take the number 412,553,155 and divide it by 2:
412,553,155 ÷ 2 = 206,276,577.5
If the quotient is a whole number, then 2 and 206,276,577.5 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 | 412,553,155 | |
| -1 | -412,553,155 |
Now, we try dividing 412,553,155 by 3:
412,553,155 ÷ 3 = 137,517,718.3333
If the quotient is a whole number, then 3 and 137,517,718.3333 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 | 412,553,155 | |
| -1 | -412,553,155 |
Let's try dividing by 4:
412,553,155 ÷ 4 = 103,138,288.75
If the quotient is a whole number, then 4 and 103,138,288.75 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 | 412,553,155 | |
| -1 | 412,553,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 283 | 1,415 | 1,981 | 9,905 | 41,651 | 208,255 | 291,557 | 1,457,785 | 11,787,233 | 58,936,165 | 82,510,631 | 412,553,155 |
| -1 | -5 | -7 | -35 | -283 | -1,415 | -1,981 | -9,905 | -41,651 | -208,255 | -291,557 | -1,457,785 | -11,787,233 | -58,936,165 | -82,510,631 | -412,553,155 |
