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 14,814,157, 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 | 14,814,157 | |
| -1 | -14,814,157 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,814,157.
Example:
1 x 14,814,157 = 14,814,157
and
-1 x -14,814,157 = 14,814,157
Notice both answers equal 14,814,157
With that explanation out of the way, let's continue. Next, we take the number 14,814,157 and divide it by 2:
14,814,157 ÷ 2 = 7,407,078.5
If the quotient is a whole number, then 2 and 7,407,078.5 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 | 14,814,157 | |
| -1 | -14,814,157 |
Now, we try dividing 14,814,157 by 3:
14,814,157 ÷ 3 = 4,938,052.3333
If the quotient is a whole number, then 3 and 4,938,052.3333 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 | 14,814,157 | |
| -1 | -14,814,157 |
Let's try dividing by 4:
14,814,157 ÷ 4 = 3,703,539.25
If the quotient is a whole number, then 4 and 3,703,539.25 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 | 14,814,157 | |
| -1 | 14,814,157 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 151 | 199 | 493 | 2,567 | 3,383 | 4,379 | 5,771 | 30,049 | 74,443 | 98,107 | 510,833 | 871,421 | 14,814,157 |
| -1 | -17 | -29 | -151 | -199 | -493 | -2,567 | -3,383 | -4,379 | -5,771 | -30,049 | -74,443 | -98,107 | -510,833 | -871,421 | -14,814,157 |
