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 14,302,105, 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 | 14,302,105 | |
| -1 | -14,302,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,302,105.
Example:
1 x 14,302,105 = 14,302,105
and
-1 x -14,302,105 = 14,302,105
Notice both answers equal 14,302,105
With that explanation out of the way, let's continue. Next, we take the number 14,302,105 and divide it by 2:
14,302,105 ÷ 2 = 7,151,052.5
If the quotient is a whole number, then 2 and 7,151,052.5 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 | 14,302,105 | |
| -1 | -14,302,105 |
Now, we try dividing 14,302,105 by 3:
14,302,105 ÷ 3 = 4,767,368.3333
If the quotient is a whole number, then 3 and 4,767,368.3333 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 | 14,302,105 | |
| -1 | -14,302,105 |
Let's try dividing by 4:
14,302,105 ÷ 4 = 3,575,526.25
If the quotient is a whole number, then 4 and 3,575,526.25 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 | 14,302,105 | |
| -1 | 14,302,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 127 | 223 | 505 | 635 | 1,115 | 12,827 | 22,523 | 28,321 | 64,135 | 112,615 | 141,605 | 2,860,421 | 14,302,105 |
| -1 | -5 | -101 | -127 | -223 | -505 | -635 | -1,115 | -12,827 | -22,523 | -28,321 | -64,135 | -112,615 | -141,605 | -2,860,421 | -14,302,105 |
