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 462,108,815, 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 | 462,108,815 | |
| -1 | -462,108,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 462,108,815.
Example:
1 x 462,108,815 = 462,108,815
and
-1 x -462,108,815 = 462,108,815
Notice both answers equal 462,108,815
With that explanation out of the way, let's continue. Next, we take the number 462,108,815 and divide it by 2:
462,108,815 ÷ 2 = 231,054,407.5
If the quotient is a whole number, then 2 and 231,054,407.5 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 | 462,108,815 | |
| -1 | -462,108,815 |
Now, we try dividing 462,108,815 by 3:
462,108,815 ÷ 3 = 154,036,271.6667
If the quotient is a whole number, then 3 and 154,036,271.6667 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 | 462,108,815 | |
| -1 | -462,108,815 |
Let's try dividing by 4:
462,108,815 ÷ 4 = 115,527,203.75
If the quotient is a whole number, then 4 and 115,527,203.75 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 | 462,108,815 | |
| -1 | 462,108,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 419 | 2,095 | 2,933 | 14,665 | 31,511 | 157,555 | 220,577 | 1,102,885 | 13,203,109 | 66,015,545 | 92,421,763 | 462,108,815 |
| -1 | -5 | -7 | -35 | -419 | -2,095 | -2,933 | -14,665 | -31,511 | -157,555 | -220,577 | -1,102,885 | -13,203,109 | -66,015,545 | -92,421,763 | -462,108,815 |
