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 1,015,703, 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 | 1,015,703 | |
| -1 | -1,015,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,015,703.
Example:
1 x 1,015,703 = 1,015,703
and
-1 x -1,015,703 = 1,015,703
Notice both answers equal 1,015,703
With that explanation out of the way, let's continue. Next, we take the number 1,015,703 and divide it by 2:
1,015,703 ÷ 2 = 507,851.5
If the quotient is a whole number, then 2 and 507,851.5 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 | 1,015,703 | |
| -1 | -1,015,703 |
Now, we try dividing 1,015,703 by 3:
1,015,703 ÷ 3 = 338,567.6667
If the quotient is a whole number, then 3 and 338,567.6667 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 | 1,015,703 | |
| -1 | -1,015,703 |
Let's try dividing by 4:
1,015,703 ÷ 4 = 253,925.75
If the quotient is a whole number, then 4 and 253,925.75 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 | 1,015,703 | |
| -1 | 1,015,703 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 79 | 299 | 559 | 989 | 1,027 | 1,817 | 3,397 | 12,857 | 23,621 | 44,161 | 78,131 | 1,015,703 |
| -1 | -13 | -23 | -43 | -79 | -299 | -559 | -989 | -1,027 | -1,817 | -3,397 | -12,857 | -23,621 | -44,161 | -78,131 | -1,015,703 |
