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 11,130,007, 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 | 11,130,007 | |
| -1 | -11,130,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,130,007.
Example:
1 x 11,130,007 = 11,130,007
and
-1 x -11,130,007 = 11,130,007
Notice both answers equal 11,130,007
With that explanation out of the way, let's continue. Next, we take the number 11,130,007 and divide it by 2:
11,130,007 ÷ 2 = 5,565,003.5
If the quotient is a whole number, then 2 and 5,565,003.5 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 | 11,130,007 | |
| -1 | -11,130,007 |
Now, we try dividing 11,130,007 by 3:
11,130,007 ÷ 3 = 3,710,002.3333
If the quotient is a whole number, then 3 and 3,710,002.3333 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 | 11,130,007 | |
| -1 | -11,130,007 |
Let's try dividing by 4:
11,130,007 ÷ 4 = 2,782,501.75
If the quotient is a whole number, then 4 and 2,782,501.75 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 | 11,130,007 | |
| -1 | 11,130,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 259 | 343 | 877 | 1,813 | 6,139 | 12,691 | 32,449 | 42,973 | 227,143 | 300,811 | 1,590,001 | 11,130,007 |
| -1 | -7 | -37 | -49 | -259 | -343 | -877 | -1,813 | -6,139 | -12,691 | -32,449 | -42,973 | -227,143 | -300,811 | -1,590,001 | -11,130,007 |
