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 462,614,815, 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 | 462,614,815 | |
| -1 | -462,614,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 462,614,815.
Example:
1 x 462,614,815 = 462,614,815
and
-1 x -462,614,815 = 462,614,815
Notice both answers equal 462,614,815
With that explanation out of the way, let's continue. Next, we take the number 462,614,815 and divide it by 2:
462,614,815 ÷ 2 = 231,307,407.5
If the quotient is a whole number, then 2 and 231,307,407.5 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 | 462,614,815 | |
| -1 | -462,614,815 |
Now, we try dividing 462,614,815 by 3:
462,614,815 ÷ 3 = 154,204,938.3333
If the quotient is a whole number, then 3 and 154,204,938.3333 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 | 462,614,815 | |
| -1 | -462,614,815 |
Let's try dividing by 4:
462,614,815 ÷ 4 = 115,653,703.75
If the quotient is a whole number, then 4 and 115,653,703.75 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 | 462,614,815 | |
| -1 | 462,614,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 245,419 | 1,227,095 | 3,190,447 | 7,117,151 | 15,952,235 | 35,585,755 | 92,522,963 | 462,614,815 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -245,419 | -1,227,095 | -3,190,447 | -7,117,151 | -15,952,235 | -35,585,755 | -92,522,963 | -462,614,815 |
