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 13,750,243, 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 | 13,750,243 | |
| -1 | -13,750,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,750,243.
Example:
1 x 13,750,243 = 13,750,243
and
-1 x -13,750,243 = 13,750,243
Notice both answers equal 13,750,243
With that explanation out of the way, let's continue. Next, we take the number 13,750,243 and divide it by 2:
13,750,243 ÷ 2 = 6,875,121.5
If the quotient is a whole number, then 2 and 6,875,121.5 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 | 13,750,243 | |
| -1 | -13,750,243 |
Now, we try dividing 13,750,243 by 3:
13,750,243 ÷ 3 = 4,583,414.3333
If the quotient is a whole number, then 3 and 4,583,414.3333 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 | 13,750,243 | |
| -1 | -13,750,243 |
Let's try dividing by 4:
13,750,243 ÷ 4 = 3,437,560.75
If the quotient is a whole number, then 4 and 3,437,560.75 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 | 13,750,243 | |
| -1 | 13,750,243 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 179 | 247 | 311 | 2,327 | 3,401 | 4,043 | 5,909 | 44,213 | 55,669 | 76,817 | 723,697 | 1,057,711 | 13,750,243 |
| -1 | -13 | -19 | -179 | -247 | -311 | -2,327 | -3,401 | -4,043 | -5,909 | -44,213 | -55,669 | -76,817 | -723,697 | -1,057,711 | -13,750,243 |
