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 410,404,315, 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 | 410,404,315 | |
| -1 | -410,404,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 410,404,315.
Example:
1 x 410,404,315 = 410,404,315
and
-1 x -410,404,315 = 410,404,315
Notice both answers equal 410,404,315
With that explanation out of the way, let's continue. Next, we take the number 410,404,315 and divide it by 2:
410,404,315 ÷ 2 = 205,202,157.5
If the quotient is a whole number, then 2 and 205,202,157.5 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 | 410,404,315 | |
| -1 | -410,404,315 |
Now, we try dividing 410,404,315 by 3:
410,404,315 ÷ 3 = 136,801,438.3333
If the quotient is a whole number, then 3 and 136,801,438.3333 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 | 410,404,315 | |
| -1 | -410,404,315 |
Let's try dividing by 4:
410,404,315 ÷ 4 = 102,601,078.75
If the quotient is a whole number, then 4 and 102,601,078.75 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 | 410,404,315 | |
| -1 | 410,404,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 4,339 | 18,917 | 21,695 | 94,585 | 82,080,863 | 410,404,315 |
| -1 | -5 | -4,339 | -18,917 | -21,695 | -94,585 | -82,080,863 | -410,404,315 |
