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 13,554,245, 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 | 13,554,245 | |
| -1 | -13,554,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,554,245.
Example:
1 x 13,554,245 = 13,554,245
and
-1 x -13,554,245 = 13,554,245
Notice both answers equal 13,554,245
With that explanation out of the way, let's continue. Next, we take the number 13,554,245 and divide it by 2:
13,554,245 ÷ 2 = 6,777,122.5
If the quotient is a whole number, then 2 and 6,777,122.5 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 | 13,554,245 | |
| -1 | -13,554,245 |
Now, we try dividing 13,554,245 by 3:
13,554,245 ÷ 3 = 4,518,081.6667
If the quotient is a whole number, then 3 and 4,518,081.6667 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 | 13,554,245 | |
| -1 | -13,554,245 |
Let's try dividing by 4:
13,554,245 ÷ 4 = 3,388,561.25
If the quotient is a whole number, then 4 and 3,388,561.25 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 | 13,554,245 | |
| -1 | 13,554,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 2,741 | 4,945 | 13,705 | 63,043 | 117,863 | 315,215 | 589,315 | 2,710,849 | 13,554,245 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -2,741 | -4,945 | -13,705 | -63,043 | -117,863 | -315,215 | -589,315 | -2,710,849 | -13,554,245 |
