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 13,316,701, 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 | 13,316,701 | |
| -1 | -13,316,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,316,701.
Example:
1 x 13,316,701 = 13,316,701
and
-1 x -13,316,701 = 13,316,701
Notice both answers equal 13,316,701
With that explanation out of the way, let's continue. Next, we take the number 13,316,701 and divide it by 2:
13,316,701 ÷ 2 = 6,658,350.5
If the quotient is a whole number, then 2 and 6,658,350.5 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 | 13,316,701 | |
| -1 | -13,316,701 |
Now, we try dividing 13,316,701 by 3:
13,316,701 ÷ 3 = 4,438,900.3333
If the quotient is a whole number, then 3 and 4,438,900.3333 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 | 13,316,701 | |
| -1 | -13,316,701 |
Let's try dividing by 4:
13,316,701 ÷ 4 = 3,329,175.25
If the quotient is a whole number, then 4 and 3,329,175.25 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 | 13,316,701 | |
| -1 | 13,316,701 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 31 | 437 | 589 | 713 | 983 | 13,547 | 18,677 | 22,609 | 30,473 | 429,571 | 578,987 | 700,879 | 13,316,701 |
| -1 | -19 | -23 | -31 | -437 | -589 | -713 | -983 | -13,547 | -18,677 | -22,609 | -30,473 | -429,571 | -578,987 | -700,879 | -13,316,701 |
