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 16,258,645, 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 | 16,258,645 | |
| -1 | -16,258,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,258,645.
Example:
1 x 16,258,645 = 16,258,645
and
-1 x -16,258,645 = 16,258,645
Notice both answers equal 16,258,645
With that explanation out of the way, let's continue. Next, we take the number 16,258,645 and divide it by 2:
16,258,645 ÷ 2 = 8,129,322.5
If the quotient is a whole number, then 2 and 8,129,322.5 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 | 16,258,645 | |
| -1 | -16,258,645 |
Now, we try dividing 16,258,645 by 3:
16,258,645 ÷ 3 = 5,419,548.3333
If the quotient is a whole number, then 3 and 5,419,548.3333 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 | 16,258,645 | |
| -1 | -16,258,645 |
Let's try dividing by 4:
16,258,645 ÷ 4 = 4,064,661.25
If the quotient is a whole number, then 4 and 4,064,661.25 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 | 16,258,645 | |
| -1 | 16,258,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 71 | 169 | 271 | 355 | 845 | 923 | 1,355 | 3,523 | 4,615 | 11,999 | 17,615 | 19,241 | 45,799 | 59,995 | 96,205 | 228,995 | 250,133 | 1,250,665 | 3,251,729 | 16,258,645 |
| -1 | -5 | -13 | -65 | -71 | -169 | -271 | -355 | -845 | -923 | -1,355 | -3,523 | -4,615 | -11,999 | -17,615 | -19,241 | -45,799 | -59,995 | -96,205 | -228,995 | -250,133 | -1,250,665 | -3,251,729 | -16,258,645 |
