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 13,554,697, 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 | 13,554,697 | |
| -1 | -13,554,697 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,554,697.
Example:
1 x 13,554,697 = 13,554,697
and
-1 x -13,554,697 = 13,554,697
Notice both answers equal 13,554,697
With that explanation out of the way, let's continue. Next, we take the number 13,554,697 and divide it by 2:
13,554,697 ÷ 2 = 6,777,348.5
If the quotient is a whole number, then 2 and 6,777,348.5 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 | 13,554,697 | |
| -1 | -13,554,697 |
Now, we try dividing 13,554,697 by 3:
13,554,697 ÷ 3 = 4,518,232.3333
If the quotient is a whole number, then 3 and 4,518,232.3333 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 | 13,554,697 | |
| -1 | -13,554,697 |
Let's try dividing by 4:
13,554,697 ÷ 4 = 3,388,674.25
If the quotient is a whole number, then 4 and 3,388,674.25 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 | 13,554,697 | |
| -1 | 13,554,697 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 103 | 191 | 689 | 1,339 | 2,483 | 5,459 | 10,123 | 19,673 | 70,967 | 131,599 | 255,749 | 1,042,669 | 13,554,697 |
| -1 | -13 | -53 | -103 | -191 | -689 | -1,339 | -2,483 | -5,459 | -10,123 | -19,673 | -70,967 | -131,599 | -255,749 | -1,042,669 | -13,554,697 |
