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 14,220,739, 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 | 14,220,739 | |
| -1 | -14,220,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,220,739.
Example:
1 x 14,220,739 = 14,220,739
and
-1 x -14,220,739 = 14,220,739
Notice both answers equal 14,220,739
With that explanation out of the way, let's continue. Next, we take the number 14,220,739 and divide it by 2:
14,220,739 ÷ 2 = 7,110,369.5
If the quotient is a whole number, then 2 and 7,110,369.5 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 | 14,220,739 | |
| -1 | -14,220,739 |
Now, we try dividing 14,220,739 by 3:
14,220,739 ÷ 3 = 4,740,246.3333
If the quotient is a whole number, then 3 and 4,740,246.3333 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 | 14,220,739 | |
| -1 | -14,220,739 |
Let's try dividing by 4:
14,220,739 ÷ 4 = 3,555,184.75
If the quotient is a whole number, then 4 and 3,555,184.75 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 | 14,220,739 | |
| -1 | 14,220,739 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 199 | 239 | 299 | 2,587 | 3,107 | 4,577 | 5,497 | 47,561 | 59,501 | 71,461 | 618,293 | 1,093,903 | 14,220,739 |
| -1 | -13 | -23 | -199 | -239 | -299 | -2,587 | -3,107 | -4,577 | -5,497 | -47,561 | -59,501 | -71,461 | -618,293 | -1,093,903 | -14,220,739 |
