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 14,798,455, 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 | 14,798,455 | |
| -1 | -14,798,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,798,455.
Example:
1 x 14,798,455 = 14,798,455
and
-1 x -14,798,455 = 14,798,455
Notice both answers equal 14,798,455
With that explanation out of the way, let's continue. Next, we take the number 14,798,455 and divide it by 2:
14,798,455 ÷ 2 = 7,399,227.5
If the quotient is a whole number, then 2 and 7,399,227.5 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 | 14,798,455 | |
| -1 | -14,798,455 |
Now, we try dividing 14,798,455 by 3:
14,798,455 ÷ 3 = 4,932,818.3333
If the quotient is a whole number, then 3 and 4,932,818.3333 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 | 14,798,455 | |
| -1 | -14,798,455 |
Let's try dividing by 4:
14,798,455 ÷ 4 = 3,699,613.75
If the quotient is a whole number, then 4 and 3,699,613.75 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 | 14,798,455 | |
| -1 | 14,798,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 563 | 751 | 2,815 | 3,755 | 3,941 | 5,257 | 19,705 | 26,285 | 422,813 | 2,114,065 | 2,959,691 | 14,798,455 |
| -1 | -5 | -7 | -35 | -563 | -751 | -2,815 | -3,755 | -3,941 | -5,257 | -19,705 | -26,285 | -422,813 | -2,114,065 | -2,959,691 | -14,798,455 |
