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 5,510,141, 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 | 5,510,141 | |
| -1 | -5,510,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,510,141.
Example:
1 x 5,510,141 = 5,510,141
and
-1 x -5,510,141 = 5,510,141
Notice both answers equal 5,510,141
With that explanation out of the way, let's continue. Next, we take the number 5,510,141 and divide it by 2:
5,510,141 ÷ 2 = 2,755,070.5
If the quotient is a whole number, then 2 and 2,755,070.5 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 | 5,510,141 | |
| -1 | -5,510,141 |
Now, we try dividing 5,510,141 by 3:
5,510,141 ÷ 3 = 1,836,713.6667
If the quotient is a whole number, then 3 and 1,836,713.6667 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 | 5,510,141 | |
| -1 | -5,510,141 |
Let's try dividing by 4:
5,510,141 ÷ 4 = 1,377,535.25
If the quotient is a whole number, then 4 and 1,377,535.25 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 | 5,510,141 | |
| -1 | 5,510,141 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 151 | 401 | 1,057 | 1,963 | 2,807 | 5,213 | 13,741 | 36,491 | 60,551 | 423,857 | 787,163 | 5,510,141 |
| -1 | -7 | -13 | -91 | -151 | -401 | -1,057 | -1,963 | -2,807 | -5,213 | -13,741 | -36,491 | -60,551 | -423,857 | -787,163 | -5,510,141 |
