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 13,794,185, 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 | 13,794,185 | |
| -1 | -13,794,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,794,185.
Example:
1 x 13,794,185 = 13,794,185
and
-1 x -13,794,185 = 13,794,185
Notice both answers equal 13,794,185
With that explanation out of the way, let's continue. Next, we take the number 13,794,185 and divide it by 2:
13,794,185 ÷ 2 = 6,897,092.5
If the quotient is a whole number, then 2 and 6,897,092.5 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 | 13,794,185 | |
| -1 | -13,794,185 |
Now, we try dividing 13,794,185 by 3:
13,794,185 ÷ 3 = 4,598,061.6667
If the quotient is a whole number, then 3 and 4,598,061.6667 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 | 13,794,185 | |
| -1 | -13,794,185 |
Let's try dividing by 4:
13,794,185 ÷ 4 = 3,448,546.25
If the quotient is a whole number, then 4 and 3,448,546.25 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 | 13,794,185 | |
| -1 | 13,794,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 83 | 215 | 415 | 773 | 3,569 | 3,865 | 17,845 | 33,239 | 64,159 | 166,195 | 320,795 | 2,758,837 | 13,794,185 |
| -1 | -5 | -43 | -83 | -215 | -415 | -773 | -3,569 | -3,865 | -17,845 | -33,239 | -64,159 | -166,195 | -320,795 | -2,758,837 | -13,794,185 |
