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 463,458,085, 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 | 463,458,085 | |
| -1 | -463,458,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 463,458,085.
Example:
1 x 463,458,085 = 463,458,085
and
-1 x -463,458,085 = 463,458,085
Notice both answers equal 463,458,085
With that explanation out of the way, let's continue. Next, we take the number 463,458,085 and divide it by 2:
463,458,085 ÷ 2 = 231,729,042.5
If the quotient is a whole number, then 2 and 231,729,042.5 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 | 463,458,085 | |
| -1 | -463,458,085 |
Now, we try dividing 463,458,085 by 3:
463,458,085 ÷ 3 = 154,486,028.3333
If the quotient is a whole number, then 3 and 154,486,028.3333 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 | 463,458,085 | |
| -1 | -463,458,085 |
Let's try dividing by 4:
463,458,085 ÷ 4 = 115,864,521.25
If the quotient is a whole number, then 4 and 115,864,521.25 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 | 463,458,085 | |
| -1 | 463,458,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 673 | 3,203 | 3,365 | 16,015 | 28,939 | 137,729 | 144,695 | 688,645 | 2,155,619 | 10,778,095 | 92,691,617 | 463,458,085 |
| -1 | -5 | -43 | -215 | -673 | -3,203 | -3,365 | -16,015 | -28,939 | -137,729 | -144,695 | -688,645 | -2,155,619 | -10,778,095 | -92,691,617 | -463,458,085 |
