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 16,669,825, 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 | 16,669,825 | |
| -1 | -16,669,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,669,825.
Example:
1 x 16,669,825 = 16,669,825
and
-1 x -16,669,825 = 16,669,825
Notice both answers equal 16,669,825
With that explanation out of the way, let's continue. Next, we take the number 16,669,825 and divide it by 2:
16,669,825 ÷ 2 = 8,334,912.5
If the quotient is a whole number, then 2 and 8,334,912.5 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 | 16,669,825 | |
| -1 | -16,669,825 |
Now, we try dividing 16,669,825 by 3:
16,669,825 ÷ 3 = 5,556,608.3333
If the quotient is a whole number, then 3 and 5,556,608.3333 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 | 16,669,825 | |
| -1 | -16,669,825 |
Let's try dividing by 4:
16,669,825 ÷ 4 = 4,167,456.25
If the quotient is a whole number, then 4 and 4,167,456.25 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 | 16,669,825 | |
| -1 | 16,669,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 53 | 115 | 265 | 547 | 575 | 1,219 | 1,325 | 2,735 | 6,095 | 12,581 | 13,675 | 28,991 | 30,475 | 62,905 | 144,955 | 314,525 | 666,793 | 724,775 | 3,333,965 | 16,669,825 |
| -1 | -5 | -23 | -25 | -53 | -115 | -265 | -547 | -575 | -1,219 | -1,325 | -2,735 | -6,095 | -12,581 | -13,675 | -28,991 | -30,475 | -62,905 | -144,955 | -314,525 | -666,793 | -724,775 | -3,333,965 | -16,669,825 |
