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 13,455,455, 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 | 13,455,455 | |
| -1 | -13,455,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,455,455.
Example:
1 x 13,455,455 = 13,455,455
and
-1 x -13,455,455 = 13,455,455
Notice both answers equal 13,455,455
With that explanation out of the way, let's continue. Next, we take the number 13,455,455 and divide it by 2:
13,455,455 ÷ 2 = 6,727,727.5
If the quotient is a whole number, then 2 and 6,727,727.5 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 | 13,455,455 | |
| -1 | -13,455,455 |
Now, we try dividing 13,455,455 by 3:
13,455,455 ÷ 3 = 4,485,151.6667
If the quotient is a whole number, then 3 and 4,485,151.6667 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 | 13,455,455 | |
| -1 | -13,455,455 |
Let's try dividing by 4:
13,455,455 ÷ 4 = 3,363,863.75
If the quotient is a whole number, then 4 and 3,363,863.75 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 | 13,455,455 | |
| -1 | 13,455,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 137 | 685 | 1,511 | 1,781 | 7,555 | 8,905 | 19,643 | 98,215 | 207,007 | 1,035,035 | 2,691,091 | 13,455,455 |
| -1 | -5 | -13 | -65 | -137 | -685 | -1,511 | -1,781 | -7,555 | -8,905 | -19,643 | -98,215 | -207,007 | -1,035,035 | -2,691,091 | -13,455,455 |
