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 487,795, 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 | 487,795 | |
| -1 | -487,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 487,795.
Example:
1 x 487,795 = 487,795
and
-1 x -487,795 = 487,795
Notice both answers equal 487,795
With that explanation out of the way, let's continue. Next, we take the number 487,795 and divide it by 2:
487,795 ÷ 2 = 243,897.5
If the quotient is a whole number, then 2 and 243,897.5 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 | 487,795 | |
| -1 | -487,795 |
Now, we try dividing 487,795 by 3:
487,795 ÷ 3 = 162,598.3333
If the quotient is a whole number, then 3 and 162,598.3333 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 | 487,795 | |
| -1 | -487,795 |
Let's try dividing by 4:
487,795 ÷ 4 = 121,948.75
If the quotient is a whole number, then 4 and 121,948.75 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 | 487,795 | |
| -1 | 487,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 181 | 245 | 385 | 539 | 905 | 1,267 | 1,991 | 2,695 | 6,335 | 8,869 | 9,955 | 13,937 | 44,345 | 69,685 | 97,559 | 487,795 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -181 | -245 | -385 | -539 | -905 | -1,267 | -1,991 | -2,695 | -6,335 | -8,869 | -9,955 | -13,937 | -44,345 | -69,685 | -97,559 | -487,795 |
