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 13,314,655, 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 | 13,314,655 | |
| -1 | -13,314,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,314,655.
Example:
1 x 13,314,655 = 13,314,655
and
-1 x -13,314,655 = 13,314,655
Notice both answers equal 13,314,655
With that explanation out of the way, let's continue. Next, we take the number 13,314,655 and divide it by 2:
13,314,655 ÷ 2 = 6,657,327.5
If the quotient is a whole number, then 2 and 6,657,327.5 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 | 13,314,655 | |
| -1 | -13,314,655 |
Now, we try dividing 13,314,655 by 3:
13,314,655 ÷ 3 = 4,438,218.3333
If the quotient is a whole number, then 3 and 4,438,218.3333 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 | 13,314,655 | |
| -1 | -13,314,655 |
Let's try dividing by 4:
13,314,655 ÷ 4 = 3,328,663.75
If the quotient is a whole number, then 4 and 3,328,663.75 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 | 13,314,655 | |
| -1 | 13,314,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 163 | 527 | 815 | 961 | 2,635 | 2,771 | 4,805 | 5,053 | 13,855 | 16,337 | 25,265 | 81,685 | 85,901 | 156,643 | 429,505 | 783,215 | 2,662,931 | 13,314,655 |
| -1 | -5 | -17 | -31 | -85 | -155 | -163 | -527 | -815 | -961 | -2,635 | -2,771 | -4,805 | -5,053 | -13,855 | -16,337 | -25,265 | -81,685 | -85,901 | -156,643 | -429,505 | -783,215 | -2,662,931 | -13,314,655 |
