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 913,913, 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 | 913,913 | |
| -1 | -913,913 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 913,913.
Example:
1 x 913,913 = 913,913
and
-1 x -913,913 = 913,913
Notice both answers equal 913,913
With that explanation out of the way, let's continue. Next, we take the number 913,913 and divide it by 2:
913,913 ÷ 2 = 456,956.5
If the quotient is a whole number, then 2 and 456,956.5 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 | 913,913 | |
| -1 | -913,913 |
Now, we try dividing 913,913 by 3:
913,913 ÷ 3 = 304,637.6667
If the quotient is a whole number, then 3 and 304,637.6667 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 | 913,913 | |
| -1 | -913,913 |
Let's try dividing by 4:
913,913 ÷ 4 = 228,478.25
If the quotient is a whole number, then 4 and 228,478.25 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 | 913,913 | |
| -1 | 913,913 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 83 | 91 | 121 | 143 | 581 | 847 | 913 | 1,001 | 1,079 | 1,573 | 6,391 | 7,553 | 10,043 | 11,011 | 11,869 | 70,301 | 83,083 | 130,559 | 913,913 |
| -1 | -7 | -11 | -13 | -77 | -83 | -91 | -121 | -143 | -581 | -847 | -913 | -1,001 | -1,079 | -1,573 | -6,391 | -7,553 | -10,043 | -11,011 | -11,869 | -70,301 | -83,083 | -130,559 | -913,913 |
