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 11,480,749, 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 | 11,480,749 | |
| -1 | -11,480,749 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,480,749.
Example:
1 x 11,480,749 = 11,480,749
and
-1 x -11,480,749 = 11,480,749
Notice both answers equal 11,480,749
With that explanation out of the way, let's continue. Next, we take the number 11,480,749 and divide it by 2:
11,480,749 ÷ 2 = 5,740,374.5
If the quotient is a whole number, then 2 and 5,740,374.5 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 | 11,480,749 | |
| -1 | -11,480,749 |
Now, we try dividing 11,480,749 by 3:
11,480,749 ÷ 3 = 3,826,916.3333
If the quotient is a whole number, then 3 and 3,826,916.3333 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 | 11,480,749 | |
| -1 | -11,480,749 |
Let's try dividing by 4:
11,480,749 ÷ 4 = 2,870,187.25
If the quotient is a whole number, then 4 and 2,870,187.25 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 | 11,480,749 | |
| -1 | 11,480,749 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 61 | 161 | 167 | 427 | 1,127 | 1,169 | 1,403 | 2,989 | 3,841 | 8,183 | 9,821 | 10,187 | 26,887 | 68,747 | 71,309 | 188,209 | 234,301 | 499,163 | 1,640,107 | 11,480,749 |
| -1 | -7 | -23 | -49 | -61 | -161 | -167 | -427 | -1,127 | -1,169 | -1,403 | -2,989 | -3,841 | -8,183 | -9,821 | -10,187 | -26,887 | -68,747 | -71,309 | -188,209 | -234,301 | -499,163 | -1,640,107 | -11,480,749 |
