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 660,695, 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 | 660,695 | |
| -1 | -660,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,695.
Example:
1 x 660,695 = 660,695
and
-1 x -660,695 = 660,695
Notice both answers equal 660,695
With that explanation out of the way, let's continue. Next, we take the number 660,695 and divide it by 2:
660,695 ÷ 2 = 330,347.5
If the quotient is a whole number, then 2 and 330,347.5 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 | 660,695 | |
| -1 | -660,695 |
Now, we try dividing 660,695 by 3:
660,695 ÷ 3 = 220,231.6667
If the quotient is a whole number, then 3 and 220,231.6667 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 | 660,695 | |
| -1 | -660,695 |
Let's try dividing by 4:
660,695 ÷ 4 = 165,173.75
If the quotient is a whole number, then 4 and 165,173.75 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 | 660,695 | |
| -1 | 660,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 439 | 1,505 | 2,195 | 3,073 | 15,365 | 18,877 | 94,385 | 132,139 | 660,695 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -439 | -1,505 | -2,195 | -3,073 | -15,365 | -18,877 | -94,385 | -132,139 | -660,695 |
