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 11,893,567, 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 | 11,893,567 | |
| -1 | -11,893,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,893,567.
Example:
1 x 11,893,567 = 11,893,567
and
-1 x -11,893,567 = 11,893,567
Notice both answers equal 11,893,567
With that explanation out of the way, let's continue. Next, we take the number 11,893,567 and divide it by 2:
11,893,567 ÷ 2 = 5,946,783.5
If the quotient is a whole number, then 2 and 5,946,783.5 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 | 11,893,567 | |
| -1 | -11,893,567 |
Now, we try dividing 11,893,567 by 3:
11,893,567 ÷ 3 = 3,964,522.3333
If the quotient is a whole number, then 3 and 3,964,522.3333 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 | 11,893,567 | |
| -1 | -11,893,567 |
Let's try dividing by 4:
11,893,567 ÷ 4 = 2,973,391.75
If the quotient is a whole number, then 4 and 2,973,391.75 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 | 11,893,567 | |
| -1 | 11,893,567 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 41 | 203 | 287 | 1,189 | 1,429 | 8,323 | 10,003 | 41,441 | 58,589 | 290,087 | 410,123 | 1,699,081 | 11,893,567 |
| -1 | -7 | -29 | -41 | -203 | -287 | -1,189 | -1,429 | -8,323 | -10,003 | -41,441 | -58,589 | -290,087 | -410,123 | -1,699,081 | -11,893,567 |
