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 16,208,629, 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 | 16,208,629 | |
| -1 | -16,208,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,208,629.
Example:
1 x 16,208,629 = 16,208,629
and
-1 x -16,208,629 = 16,208,629
Notice both answers equal 16,208,629
With that explanation out of the way, let's continue. Next, we take the number 16,208,629 and divide it by 2:
16,208,629 ÷ 2 = 8,104,314.5
If the quotient is a whole number, then 2 and 8,104,314.5 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 | 16,208,629 | |
| -1 | -16,208,629 |
Now, we try dividing 16,208,629 by 3:
16,208,629 ÷ 3 = 5,402,876.3333
If the quotient is a whole number, then 3 and 5,402,876.3333 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 | 16,208,629 | |
| -1 | -16,208,629 |
Let's try dividing by 4:
16,208,629 ÷ 4 = 4,052,157.25
If the quotient is a whole number, then 4 and 4,052,157.25 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 | 16,208,629 | |
| -1 | 16,208,629 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 127 | 179 | 713 | 2,921 | 3,937 | 4,117 | 5,549 | 22,733 | 90,551 | 127,627 | 522,859 | 704,723 | 16,208,629 |
| -1 | -23 | -31 | -127 | -179 | -713 | -2,921 | -3,937 | -4,117 | -5,549 | -22,733 | -90,551 | -127,627 | -522,859 | -704,723 | -16,208,629 |
