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 710,515, 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 | 710,515 | |
| -1 | -710,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 710,515.
Example:
1 x 710,515 = 710,515
and
-1 x -710,515 = 710,515
Notice both answers equal 710,515
With that explanation out of the way, let's continue. Next, we take the number 710,515 and divide it by 2:
710,515 ÷ 2 = 355,257.5
If the quotient is a whole number, then 2 and 355,257.5 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 | 710,515 | |
| -1 | -710,515 |
Now, we try dividing 710,515 by 3:
710,515 ÷ 3 = 236,838.3333
If the quotient is a whole number, then 3 and 236,838.3333 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 | 710,515 | |
| -1 | -710,515 |
Let's try dividing by 4:
710,515 ÷ 4 = 177,628.75
If the quotient is a whole number, then 4 and 177,628.75 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 | 710,515 | |
| -1 | 710,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 643 | 1,105 | 3,215 | 8,359 | 10,931 | 41,795 | 54,655 | 142,103 | 710,515 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -643 | -1,105 | -3,215 | -8,359 | -10,931 | -41,795 | -54,655 | -142,103 | -710,515 |
