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 445,466,231, 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 | 445,466,231 | |
| -1 | -445,466,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 445,466,231.
Example:
1 x 445,466,231 = 445,466,231
and
-1 x -445,466,231 = 445,466,231
Notice both answers equal 445,466,231
With that explanation out of the way, let's continue. Next, we take the number 445,466,231 and divide it by 2:
445,466,231 ÷ 2 = 222,733,115.5
If the quotient is a whole number, then 2 and 222,733,115.5 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 | 445,466,231 | |
| -1 | -445,466,231 |
Now, we try dividing 445,466,231 by 3:
445,466,231 ÷ 3 = 148,488,743.6667
If the quotient is a whole number, then 3 and 148,488,743.6667 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 | 445,466,231 | |
| -1 | -445,466,231 |
Let's try dividing by 4:
445,466,231 ÷ 4 = 111,366,557.75
If the quotient is a whole number, then 4 and 111,366,557.75 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 | 445,466,231 | |
| -1 | 445,466,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 1,619 | 1,709 | 11,333 | 11,963 | 37,237 | 39,307 | 260,659 | 275,149 | 2,766,871 | 19,368,097 | 63,638,033 | 445,466,231 |
| -1 | -7 | -23 | -161 | -1,619 | -1,709 | -11,333 | -11,963 | -37,237 | -39,307 | -260,659 | -275,149 | -2,766,871 | -19,368,097 | -63,638,033 | -445,466,231 |
