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 13,627,355, 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 | 13,627,355 | |
| -1 | -13,627,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,627,355.
Example:
1 x 13,627,355 = 13,627,355
and
-1 x -13,627,355 = 13,627,355
Notice both answers equal 13,627,355
With that explanation out of the way, let's continue. Next, we take the number 13,627,355 and divide it by 2:
13,627,355 ÷ 2 = 6,813,677.5
If the quotient is a whole number, then 2 and 6,813,677.5 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 | 13,627,355 | |
| -1 | -13,627,355 |
Now, we try dividing 13,627,355 by 3:
13,627,355 ÷ 3 = 4,542,451.6667
If the quotient is a whole number, then 3 and 4,542,451.6667 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 | 13,627,355 | |
| -1 | -13,627,355 |
Let's try dividing by 4:
13,627,355 ÷ 4 = 3,406,838.75
If the quotient is a whole number, then 4 and 3,406,838.75 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 | 13,627,355 | |
| -1 | 13,627,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 83 | 415 | 581 | 2,905 | 4,691 | 23,455 | 32,837 | 164,185 | 389,353 | 1,946,765 | 2,725,471 | 13,627,355 |
| -1 | -5 | -7 | -35 | -83 | -415 | -581 | -2,905 | -4,691 | -23,455 | -32,837 | -164,185 | -389,353 | -1,946,765 | -2,725,471 | -13,627,355 |
