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 14,996,905, 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 | 14,996,905 | |
| -1 | -14,996,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,996,905.
Example:
1 x 14,996,905 = 14,996,905
and
-1 x -14,996,905 = 14,996,905
Notice both answers equal 14,996,905
With that explanation out of the way, let's continue. Next, we take the number 14,996,905 and divide it by 2:
14,996,905 ÷ 2 = 7,498,452.5
If the quotient is a whole number, then 2 and 7,498,452.5 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 | 14,996,905 | |
| -1 | -14,996,905 |
Now, we try dividing 14,996,905 by 3:
14,996,905 ÷ 3 = 4,998,968.3333
If the quotient is a whole number, then 3 and 4,998,968.3333 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 | 14,996,905 | |
| -1 | -14,996,905 |
Let's try dividing by 4:
14,996,905 ÷ 4 = 3,749,226.25
If the quotient is a whole number, then 4 and 3,749,226.25 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 | 14,996,905 | |
| -1 | 14,996,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 38,953 | 194,765 | 272,671 | 428,483 | 1,363,355 | 2,142,415 | 2,999,381 | 14,996,905 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -38,953 | -194,765 | -272,671 | -428,483 | -1,363,355 | -2,142,415 | -2,999,381 | -14,996,905 |
