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 11,030,545, 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 | 11,030,545 | |
| -1 | -11,030,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,030,545.
Example:
1 x 11,030,545 = 11,030,545
and
-1 x -11,030,545 = 11,030,545
Notice both answers equal 11,030,545
With that explanation out of the way, let's continue. Next, we take the number 11,030,545 and divide it by 2:
11,030,545 ÷ 2 = 5,515,272.5
If the quotient is a whole number, then 2 and 5,515,272.5 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 | 11,030,545 | |
| -1 | -11,030,545 |
Now, we try dividing 11,030,545 by 3:
11,030,545 ÷ 3 = 3,676,848.3333
If the quotient is a whole number, then 3 and 3,676,848.3333 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 | 11,030,545 | |
| -1 | -11,030,545 |
Let's try dividing by 4:
11,030,545 ÷ 4 = 2,757,636.25
If the quotient is a whole number, then 4 and 2,757,636.25 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 | 11,030,545 | |
| -1 | 11,030,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 67 | 95 | 335 | 1,273 | 1,733 | 6,365 | 8,665 | 32,927 | 116,111 | 164,635 | 580,555 | 2,206,109 | 11,030,545 |
| -1 | -5 | -19 | -67 | -95 | -335 | -1,273 | -1,733 | -6,365 | -8,665 | -32,927 | -116,111 | -164,635 | -580,555 | -2,206,109 | -11,030,545 |
