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 1,030,315, 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 | 1,030,315 | |
| -1 | -1,030,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,030,315.
Example:
1 x 1,030,315 = 1,030,315
and
-1 x -1,030,315 = 1,030,315
Notice both answers equal 1,030,315
With that explanation out of the way, let's continue. Next, we take the number 1,030,315 and divide it by 2:
1,030,315 ÷ 2 = 515,157.5
If the quotient is a whole number, then 2 and 515,157.5 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 | 1,030,315 | |
| -1 | -1,030,315 |
Now, we try dividing 1,030,315 by 3:
1,030,315 ÷ 3 = 343,438.3333
If the quotient is a whole number, then 3 and 343,438.3333 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 | 1,030,315 | |
| -1 | -1,030,315 |
Let's try dividing by 4:
1,030,315 ÷ 4 = 257,578.75
If the quotient is a whole number, then 4 and 257,578.75 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 | 1,030,315 | |
| -1 | 1,030,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 131 | 143 | 605 | 655 | 715 | 1,441 | 1,573 | 1,703 | 7,205 | 7,865 | 8,515 | 15,851 | 18,733 | 79,255 | 93,665 | 206,063 | 1,030,315 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -131 | -143 | -605 | -655 | -715 | -1,441 | -1,573 | -1,703 | -7,205 | -7,865 | -8,515 | -15,851 | -18,733 | -79,255 | -93,665 | -206,063 | -1,030,315 |
