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 435,331,145, 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 | 435,331,145 | |
| -1 | -435,331,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 435,331,145.
Example:
1 x 435,331,145 = 435,331,145
and
-1 x -435,331,145 = 435,331,145
Notice both answers equal 435,331,145
With that explanation out of the way, let's continue. Next, we take the number 435,331,145 and divide it by 2:
435,331,145 ÷ 2 = 217,665,572.5
If the quotient is a whole number, then 2 and 217,665,572.5 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 | 435,331,145 | |
| -1 | -435,331,145 |
Now, we try dividing 435,331,145 by 3:
435,331,145 ÷ 3 = 145,110,381.6667
If the quotient is a whole number, then 3 and 145,110,381.6667 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 | 435,331,145 | |
| -1 | -435,331,145 |
Let's try dividing by 4:
435,331,145 ÷ 4 = 108,832,786.25
If the quotient is a whole number, then 4 and 108,832,786.25 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 | 435,331,145 | |
| -1 | 435,331,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 173 | 613 | 821 | 865 | 3,065 | 4,105 | 106,049 | 142,033 | 503,273 | 530,245 | 710,165 | 2,516,365 | 87,066,229 | 435,331,145 |
| -1 | -5 | -173 | -613 | -821 | -865 | -3,065 | -4,105 | -106,049 | -142,033 | -503,273 | -530,245 | -710,165 | -2,516,365 | -87,066,229 | -435,331,145 |
