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 405,310,133, 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 | 405,310,133 | |
| -1 | -405,310,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 405,310,133.
Example:
1 x 405,310,133 = 405,310,133
and
-1 x -405,310,133 = 405,310,133
Notice both answers equal 405,310,133
With that explanation out of the way, let's continue. Next, we take the number 405,310,133 and divide it by 2:
405,310,133 ÷ 2 = 202,655,066.5
If the quotient is a whole number, then 2 and 202,655,066.5 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 | 405,310,133 | |
| -1 | -405,310,133 |
Now, we try dividing 405,310,133 by 3:
405,310,133 ÷ 3 = 135,103,377.6667
If the quotient is a whole number, then 3 and 135,103,377.6667 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 | 405,310,133 | |
| -1 | -405,310,133 |
Let's try dividing by 4:
405,310,133 ÷ 4 = 101,327,533.25
If the quotient is a whole number, then 4 and 101,327,533.25 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 | 405,310,133 | |
| -1 | 405,310,133 |
If you did it right, you will end up with this table:
| 1 | 41 | 53 | 383 | 487 | 2,173 | 15,703 | 19,967 | 20,299 | 25,811 | 186,521 | 832,259 | 1,058,251 | 7,647,361 | 9,885,613 | 405,310,133 |
| -1 | -41 | -53 | -383 | -487 | -2,173 | -15,703 | -19,967 | -20,299 | -25,811 | -186,521 | -832,259 | -1,058,251 | -7,647,361 | -9,885,613 | -405,310,133 |
