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 14,949,415, 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 | 14,949,415 | |
| -1 | -14,949,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,949,415.
Example:
1 x 14,949,415 = 14,949,415
and
-1 x -14,949,415 = 14,949,415
Notice both answers equal 14,949,415
With that explanation out of the way, let's continue. Next, we take the number 14,949,415 and divide it by 2:
14,949,415 ÷ 2 = 7,474,707.5
If the quotient is a whole number, then 2 and 7,474,707.5 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 | 14,949,415 | |
| -1 | -14,949,415 |
Now, we try dividing 14,949,415 by 3:
14,949,415 ÷ 3 = 4,983,138.3333
If the quotient is a whole number, then 3 and 4,983,138.3333 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 | 14,949,415 | |
| -1 | -14,949,415 |
Let's try dividing by 4:
14,949,415 ÷ 4 = 3,737,353.75
If the quotient is a whole number, then 4 and 3,737,353.75 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 | 14,949,415 | |
| -1 | 14,949,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 349 | 659 | 1,745 | 3,295 | 4,537 | 8,567 | 22,685 | 42,835 | 229,991 | 1,149,955 | 2,989,883 | 14,949,415 |
| -1 | -5 | -13 | -65 | -349 | -659 | -1,745 | -3,295 | -4,537 | -8,567 | -22,685 | -42,835 | -229,991 | -1,149,955 | -2,989,883 | -14,949,415 |
