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 13,546,247, 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 | 13,546,247 | |
| -1 | -13,546,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,546,247.
Example:
1 x 13,546,247 = 13,546,247
and
-1 x -13,546,247 = 13,546,247
Notice both answers equal 13,546,247
With that explanation out of the way, let's continue. Next, we take the number 13,546,247 and divide it by 2:
13,546,247 ÷ 2 = 6,773,123.5
If the quotient is a whole number, then 2 and 6,773,123.5 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 | 13,546,247 | |
| -1 | -13,546,247 |
Now, we try dividing 13,546,247 by 3:
13,546,247 ÷ 3 = 4,515,415.6667
If the quotient is a whole number, then 3 and 4,515,415.6667 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 | 13,546,247 | |
| -1 | -13,546,247 |
Let's try dividing by 4:
13,546,247 ÷ 4 = 3,386,561.75
If the quotient is a whole number, then 4 and 3,386,561.75 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 | 13,546,247 | |
| -1 | 13,546,247 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 43 | 143 | 473 | 559 | 2,203 | 6,149 | 24,233 | 28,639 | 94,729 | 315,029 | 1,042,019 | 1,231,477 | 13,546,247 |
| -1 | -11 | -13 | -43 | -143 | -473 | -559 | -2,203 | -6,149 | -24,233 | -28,639 | -94,729 | -315,029 | -1,042,019 | -1,231,477 | -13,546,247 |
