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 12,151,469, 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 | 12,151,469 | |
| -1 | -12,151,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,151,469.
Example:
1 x 12,151,469 = 12,151,469
and
-1 x -12,151,469 = 12,151,469
Notice both answers equal 12,151,469
With that explanation out of the way, let's continue. Next, we take the number 12,151,469 and divide it by 2:
12,151,469 ÷ 2 = 6,075,734.5
If the quotient is a whole number, then 2 and 6,075,734.5 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 | 12,151,469 | |
| -1 | -12,151,469 |
Now, we try dividing 12,151,469 by 3:
12,151,469 ÷ 3 = 4,050,489.6667
If the quotient is a whole number, then 3 and 4,050,489.6667 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 | 12,151,469 | |
| -1 | -12,151,469 |
Let's try dividing by 4:
12,151,469 ÷ 4 = 3,037,867.25
If the quotient is a whole number, then 4 and 3,037,867.25 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 | 12,151,469 | |
| -1 | 12,151,469 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 53 | 209 | 583 | 1,007 | 1,097 | 11,077 | 12,067 | 20,843 | 58,141 | 229,273 | 639,551 | 1,104,679 | 12,151,469 |
| -1 | -11 | -19 | -53 | -209 | -583 | -1,007 | -1,097 | -11,077 | -12,067 | -20,843 | -58,141 | -229,273 | -639,551 | -1,104,679 | -12,151,469 |
