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 13,813,735, 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 | 13,813,735 | |
| -1 | -13,813,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,813,735.
Example:
1 x 13,813,735 = 13,813,735
and
-1 x -13,813,735 = 13,813,735
Notice both answers equal 13,813,735
With that explanation out of the way, let's continue. Next, we take the number 13,813,735 and divide it by 2:
13,813,735 ÷ 2 = 6,906,867.5
If the quotient is a whole number, then 2 and 6,906,867.5 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 | 13,813,735 | |
| -1 | -13,813,735 |
Now, we try dividing 13,813,735 by 3:
13,813,735 ÷ 3 = 4,604,578.3333
If the quotient is a whole number, then 3 and 4,604,578.3333 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 | 13,813,735 | |
| -1 | -13,813,735 |
Let's try dividing by 4:
13,813,735 ÷ 4 = 3,453,433.75
If the quotient is a whole number, then 4 and 3,453,433.75 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 | 13,813,735 | |
| -1 | 13,813,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 223 | 953 | 1,115 | 2,899 | 4,765 | 12,389 | 14,495 | 61,945 | 212,519 | 1,062,595 | 2,762,747 | 13,813,735 |
| -1 | -5 | -13 | -65 | -223 | -953 | -1,115 | -2,899 | -4,765 | -12,389 | -14,495 | -61,945 | -212,519 | -1,062,595 | -2,762,747 | -13,813,735 |
