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 585,086,545, 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 | 585,086,545 | |
| -1 | -585,086,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 585,086,545.
Example:
1 x 585,086,545 = 585,086,545
and
-1 x -585,086,545 = 585,086,545
Notice both answers equal 585,086,545
With that explanation out of the way, let's continue. Next, we take the number 585,086,545 and divide it by 2:
585,086,545 ÷ 2 = 292,543,272.5
If the quotient is a whole number, then 2 and 292,543,272.5 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 | 585,086,545 | |
| -1 | -585,086,545 |
Now, we try dividing 585,086,545 by 3:
585,086,545 ÷ 3 = 195,028,848.3333
If the quotient is a whole number, then 3 and 195,028,848.3333 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 | 585,086,545 | |
| -1 | -585,086,545 |
Let's try dividing by 4:
585,086,545 ÷ 4 = 146,271,636.25
If the quotient is a whole number, then 4 and 146,271,636.25 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 | 585,086,545 | |
| -1 | 585,086,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 241 | 335 | 1,205 | 7,247 | 16,147 | 36,235 | 80,735 | 485,549 | 1,746,527 | 2,427,745 | 8,732,635 | 117,017,309 | 585,086,545 |
| -1 | -5 | -67 | -241 | -335 | -1,205 | -7,247 | -16,147 | -36,235 | -80,735 | -485,549 | -1,746,527 | -2,427,745 | -8,732,635 | -117,017,309 | -585,086,545 |
