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 14,540,155, 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 | 14,540,155 | |
| -1 | -14,540,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,540,155.
Example:
1 x 14,540,155 = 14,540,155
and
-1 x -14,540,155 = 14,540,155
Notice both answers equal 14,540,155
With that explanation out of the way, let's continue. Next, we take the number 14,540,155 and divide it by 2:
14,540,155 ÷ 2 = 7,270,077.5
If the quotient is a whole number, then 2 and 7,270,077.5 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 | 14,540,155 | |
| -1 | -14,540,155 |
Now, we try dividing 14,540,155 by 3:
14,540,155 ÷ 3 = 4,846,718.3333
If the quotient is a whole number, then 3 and 4,846,718.3333 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 | 14,540,155 | |
| -1 | -14,540,155 |
Let's try dividing by 4:
14,540,155 ÷ 4 = 3,635,038.75
If the quotient is a whole number, then 4 and 3,635,038.75 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 | 14,540,155 | |
| -1 | 14,540,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 8,839 | 44,195 | 61,873 | 309,365 | 415,433 | 2,077,165 | 2,908,031 | 14,540,155 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -8,839 | -44,195 | -61,873 | -309,365 | -415,433 | -2,077,165 | -2,908,031 | -14,540,155 |
