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 11,224,711, 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 | 11,224,711 | |
| -1 | -11,224,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,224,711.
Example:
1 x 11,224,711 = 11,224,711
and
-1 x -11,224,711 = 11,224,711
Notice both answers equal 11,224,711
With that explanation out of the way, let's continue. Next, we take the number 11,224,711 and divide it by 2:
11,224,711 ÷ 2 = 5,612,355.5
If the quotient is a whole number, then 2 and 5,612,355.5 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 | 11,224,711 | |
| -1 | -11,224,711 |
Now, we try dividing 11,224,711 by 3:
11,224,711 ÷ 3 = 3,741,570.3333
If the quotient is a whole number, then 3 and 3,741,570.3333 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 | 11,224,711 | |
| -1 | -11,224,711 |
Let's try dividing by 4:
11,224,711 ÷ 4 = 2,806,177.75
If the quotient is a whole number, then 4 and 2,806,177.75 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 | 11,224,711 | |
| -1 | 11,224,711 |
If you did it right, you will end up with this table:
| 1 | 29 | 53 | 67 | 109 | 1,537 | 1,943 | 3,161 | 3,551 | 5,777 | 7,303 | 102,979 | 167,533 | 211,787 | 387,059 | 11,224,711 |
| -1 | -29 | -53 | -67 | -109 | -1,537 | -1,943 | -3,161 | -3,551 | -5,777 | -7,303 | -102,979 | -167,533 | -211,787 | -387,059 | -11,224,711 |
