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 13,753,187, 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 | 13,753,187 | |
| -1 | -13,753,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,753,187.
Example:
1 x 13,753,187 = 13,753,187
and
-1 x -13,753,187 = 13,753,187
Notice both answers equal 13,753,187
With that explanation out of the way, let's continue. Next, we take the number 13,753,187 and divide it by 2:
13,753,187 ÷ 2 = 6,876,593.5
If the quotient is a whole number, then 2 and 6,876,593.5 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 | 13,753,187 | |
| -1 | -13,753,187 |
Now, we try dividing 13,753,187 by 3:
13,753,187 ÷ 3 = 4,584,395.6667
If the quotient is a whole number, then 3 and 4,584,395.6667 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 | 13,753,187 | |
| -1 | -13,753,187 |
Let's try dividing by 4:
13,753,187 ÷ 4 = 3,438,296.75
If the quotient is a whole number, then 4 and 3,438,296.75 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 | 13,753,187 | |
| -1 | 13,753,187 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 47 | 119 | 329 | 799 | 2,459 | 5,593 | 17,213 | 41,803 | 115,573 | 292,621 | 809,011 | 1,964,741 | 13,753,187 |
| -1 | -7 | -17 | -47 | -119 | -329 | -799 | -2,459 | -5,593 | -17,213 | -41,803 | -115,573 | -292,621 | -809,011 | -1,964,741 | -13,753,187 |
