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 1,310,335, 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 | 1,310,335 | |
| -1 | -1,310,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,310,335.
Example:
1 x 1,310,335 = 1,310,335
and
-1 x -1,310,335 = 1,310,335
Notice both answers equal 1,310,335
With that explanation out of the way, let's continue. Next, we take the number 1,310,335 and divide it by 2:
1,310,335 ÷ 2 = 655,167.5
If the quotient is a whole number, then 2 and 655,167.5 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 | 1,310,335 | |
| -1 | -1,310,335 |
Now, we try dividing 1,310,335 by 3:
1,310,335 ÷ 3 = 436,778.3333
If the quotient is a whole number, then 3 and 436,778.3333 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 | 1,310,335 | |
| -1 | -1,310,335 |
Let's try dividing by 4:
1,310,335 ÷ 4 = 327,583.75
If the quotient is a whole number, then 4 and 327,583.75 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 | 1,310,335 | |
| -1 | 1,310,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,061 | 1,235 | 5,305 | 13,793 | 20,159 | 68,965 | 100,795 | 262,067 | 1,310,335 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,061 | -1,235 | -5,305 | -13,793 | -20,159 | -68,965 | -100,795 | -262,067 | -1,310,335 |
