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 1,314,515, 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 | 1,314,515 | |
| -1 | -1,314,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,314,515.
Example:
1 x 1,314,515 = 1,314,515
and
-1 x -1,314,515 = 1,314,515
Notice both answers equal 1,314,515
With that explanation out of the way, let's continue. Next, we take the number 1,314,515 and divide it by 2:
1,314,515 ÷ 2 = 657,257.5
If the quotient is a whole number, then 2 and 657,257.5 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 | 1,314,515 | |
| -1 | -1,314,515 |
Now, we try dividing 1,314,515 by 3:
1,314,515 ÷ 3 = 438,171.6667
If the quotient is a whole number, then 3 and 438,171.6667 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 | 1,314,515 | |
| -1 | -1,314,515 |
Let's try dividing by 4:
1,314,515 ÷ 4 = 328,628.75
If the quotient is a whole number, then 4 and 328,628.75 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 | 1,314,515 | |
| -1 | 1,314,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 101 | 137 | 505 | 685 | 1,919 | 2,603 | 9,595 | 13,015 | 13,837 | 69,185 | 262,903 | 1,314,515 |
| -1 | -5 | -19 | -95 | -101 | -137 | -505 | -685 | -1,919 | -2,603 | -9,595 | -13,015 | -13,837 | -69,185 | -262,903 | -1,314,515 |
