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 1,513,901, 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 | 1,513,901 | |
| -1 | -1,513,901 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,513,901.
Example:
1 x 1,513,901 = 1,513,901
and
-1 x -1,513,901 = 1,513,901
Notice both answers equal 1,513,901
With that explanation out of the way, let's continue. Next, we take the number 1,513,901 and divide it by 2:
1,513,901 ÷ 2 = 756,950.5
If the quotient is a whole number, then 2 and 756,950.5 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 | 1,513,901 | |
| -1 | -1,513,901 |
Now, we try dividing 1,513,901 by 3:
1,513,901 ÷ 3 = 504,633.6667
If the quotient is a whole number, then 3 and 504,633.6667 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 | 1,513,901 | |
| -1 | -1,513,901 |
Let's try dividing by 4:
1,513,901 ÷ 4 = 378,475.25
If the quotient is a whole number, then 4 and 378,475.25 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 | 1,513,901 | |
| -1 | 1,513,901 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 43 | 109 | 323 | 731 | 817 | 1,853 | 2,071 | 4,687 | 13,889 | 35,207 | 79,679 | 89,053 | 1,513,901 |
| -1 | -17 | -19 | -43 | -109 | -323 | -731 | -817 | -1,853 | -2,071 | -4,687 | -13,889 | -35,207 | -79,679 | -89,053 | -1,513,901 |
