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 5,105,045, 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 | 5,105,045 | |
| -1 | -5,105,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,105,045.
Example:
1 x 5,105,045 = 5,105,045
and
-1 x -5,105,045 = 5,105,045
Notice both answers equal 5,105,045
With that explanation out of the way, let's continue. Next, we take the number 5,105,045 and divide it by 2:
5,105,045 ÷ 2 = 2,552,522.5
If the quotient is a whole number, then 2 and 2,552,522.5 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 | 5,105,045 | |
| -1 | -5,105,045 |
Now, we try dividing 5,105,045 by 3:
5,105,045 ÷ 3 = 1,701,681.6667
If the quotient is a whole number, then 3 and 1,701,681.6667 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 | 5,105,045 | |
| -1 | -5,105,045 |
Let's try dividing by 4:
5,105,045 ÷ 4 = 1,276,261.25
If the quotient is a whole number, then 4 and 1,276,261.25 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 | 5,105,045 | |
| -1 | 5,105,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 505 | 919 | 1,111 | 4,595 | 5,555 | 10,109 | 50,545 | 92,819 | 464,095 | 1,021,009 | 5,105,045 |
| -1 | -5 | -11 | -55 | -101 | -505 | -919 | -1,111 | -4,595 | -5,555 | -10,109 | -50,545 | -92,819 | -464,095 | -1,021,009 | -5,105,045 |
