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 664,895, 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 | 664,895 | |
| -1 | -664,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 664,895.
Example:
1 x 664,895 = 664,895
and
-1 x -664,895 = 664,895
Notice both answers equal 664,895
With that explanation out of the way, let's continue. Next, we take the number 664,895 and divide it by 2:
664,895 ÷ 2 = 332,447.5
If the quotient is a whole number, then 2 and 332,447.5 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 | 664,895 | |
| -1 | -664,895 |
Now, we try dividing 664,895 by 3:
664,895 ÷ 3 = 221,631.6667
If the quotient is a whole number, then 3 and 221,631.6667 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 | 664,895 | |
| -1 | -664,895 |
Let's try dividing by 4:
664,895 ÷ 4 = 166,223.75
If the quotient is a whole number, then 4 and 166,223.75 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 | 664,895 | |
| -1 | 664,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 157 | 385 | 605 | 785 | 847 | 1,099 | 1,727 | 4,235 | 5,495 | 8,635 | 12,089 | 18,997 | 60,445 | 94,985 | 132,979 | 664,895 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -157 | -385 | -605 | -785 | -847 | -1,099 | -1,727 | -4,235 | -5,495 | -8,635 | -12,089 | -18,997 | -60,445 | -94,985 | -132,979 | -664,895 |
