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 660,462,257, 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 | 660,462,257 | |
| -1 | -660,462,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,462,257.
Example:
1 x 660,462,257 = 660,462,257
and
-1 x -660,462,257 = 660,462,257
Notice both answers equal 660,462,257
With that explanation out of the way, let's continue. Next, we take the number 660,462,257 and divide it by 2:
660,462,257 ÷ 2 = 330,231,128.5
If the quotient is a whole number, then 2 and 330,231,128.5 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 | 660,462,257 | |
| -1 | -660,462,257 |
Now, we try dividing 660,462,257 by 3:
660,462,257 ÷ 3 = 220,154,085.6667
If the quotient is a whole number, then 3 and 220,154,085.6667 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 | 660,462,257 | |
| -1 | -660,462,257 |
Let's try dividing by 4:
660,462,257 ÷ 4 = 165,115,564.25
If the quotient is a whole number, then 4 and 165,115,564.25 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 | 660,462,257 | |
| -1 | 660,462,257 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 426,931 | 2,988,517 | 5,550,103 | 7,257,827 | 38,850,721 | 50,804,789 | 94,351,751 | 660,462,257 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -426,931 | -2,988,517 | -5,550,103 | -7,257,827 | -38,850,721 | -50,804,789 | -94,351,751 | -660,462,257 |
