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 13,517,119, 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 | 13,517,119 | |
| -1 | -13,517,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,517,119.
Example:
1 x 13,517,119 = 13,517,119
and
-1 x -13,517,119 = 13,517,119
Notice both answers equal 13,517,119
With that explanation out of the way, let's continue. Next, we take the number 13,517,119 and divide it by 2:
13,517,119 ÷ 2 = 6,758,559.5
If the quotient is a whole number, then 2 and 6,758,559.5 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 | 13,517,119 | |
| -1 | -13,517,119 |
Now, we try dividing 13,517,119 by 3:
13,517,119 ÷ 3 = 4,505,706.3333
If the quotient is a whole number, then 3 and 4,505,706.3333 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 | 13,517,119 | |
| -1 | -13,517,119 |
Let's try dividing by 4:
13,517,119 ÷ 4 = 3,379,279.75
If the quotient is a whole number, then 4 and 3,379,279.75 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 | 13,517,119 | |
| -1 | 13,517,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 349 | 503 | 2,443 | 3,521 | 3,839 | 5,533 | 26,873 | 38,731 | 175,547 | 1,228,829 | 1,931,017 | 13,517,119 |
| -1 | -7 | -11 | -77 | -349 | -503 | -2,443 | -3,521 | -3,839 | -5,533 | -26,873 | -38,731 | -175,547 | -1,228,829 | -1,931,017 | -13,517,119 |
