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 11,343,409, 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 | 11,343,409 | |
| -1 | -11,343,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,343,409.
Example:
1 x 11,343,409 = 11,343,409
and
-1 x -11,343,409 = 11,343,409
Notice both answers equal 11,343,409
With that explanation out of the way, let's continue. Next, we take the number 11,343,409 and divide it by 2:
11,343,409 ÷ 2 = 5,671,704.5
If the quotient is a whole number, then 2 and 5,671,704.5 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 | 11,343,409 | |
| -1 | -11,343,409 |
Now, we try dividing 11,343,409 by 3:
11,343,409 ÷ 3 = 3,781,136.3333
If the quotient is a whole number, then 3 and 3,781,136.3333 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 | 11,343,409 | |
| -1 | -11,343,409 |
Let's try dividing by 4:
11,343,409 ÷ 4 = 2,835,852.25
If the quotient is a whole number, then 4 and 2,835,852.25 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 | 11,343,409 | |
| -1 | 11,343,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 179 | 823 | 1,253 | 1,969 | 5,761 | 9,053 | 13,783 | 63,371 | 147,317 | 1,031,219 | 1,620,487 | 11,343,409 |
| -1 | -7 | -11 | -77 | -179 | -823 | -1,253 | -1,969 | -5,761 | -9,053 | -13,783 | -63,371 | -147,317 | -1,031,219 | -1,620,487 | -11,343,409 |
