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 16,301,351, 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 | 16,301,351 | |
| -1 | -16,301,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,301,351.
Example:
1 x 16,301,351 = 16,301,351
and
-1 x -16,301,351 = 16,301,351
Notice both answers equal 16,301,351
With that explanation out of the way, let's continue. Next, we take the number 16,301,351 and divide it by 2:
16,301,351 ÷ 2 = 8,150,675.5
If the quotient is a whole number, then 2 and 8,150,675.5 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 | 16,301,351 | |
| -1 | -16,301,351 |
Now, we try dividing 16,301,351 by 3:
16,301,351 ÷ 3 = 5,433,783.6667
If the quotient is a whole number, then 3 and 5,433,783.6667 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 | 16,301,351 | |
| -1 | -16,301,351 |
Let's try dividing by 4:
16,301,351 ÷ 4 = 4,075,337.75
If the quotient is a whole number, then 4 and 4,075,337.75 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 | 16,301,351 | |
| -1 | 16,301,351 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 179 | 187 | 487 | 1,969 | 3,043 | 5,357 | 8,279 | 33,473 | 87,173 | 91,069 | 958,903 | 1,481,941 | 16,301,351 |
| -1 | -11 | -17 | -179 | -187 | -487 | -1,969 | -3,043 | -5,357 | -8,279 | -33,473 | -87,173 | -91,069 | -958,903 | -1,481,941 | -16,301,351 |
