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 16,670,285, 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 | 16,670,285 | |
| -1 | -16,670,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,670,285.
Example:
1 x 16,670,285 = 16,670,285
and
-1 x -16,670,285 = 16,670,285
Notice both answers equal 16,670,285
With that explanation out of the way, let's continue. Next, we take the number 16,670,285 and divide it by 2:
16,670,285 ÷ 2 = 8,335,142.5
If the quotient is a whole number, then 2 and 8,335,142.5 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 | 16,670,285 | |
| -1 | -16,670,285 |
Now, we try dividing 16,670,285 by 3:
16,670,285 ÷ 3 = 5,556,761.6667
If the quotient is a whole number, then 3 and 5,556,761.6667 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 | 16,670,285 | |
| -1 | -16,670,285 |
Let's try dividing by 4:
16,670,285 ÷ 4 = 4,167,571.25
If the quotient is a whole number, then 4 and 4,167,571.25 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 | 16,670,285 | |
| -1 | 16,670,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 8,527 | 42,635 | 144,959 | 196,121 | 724,795 | 980,605 | 3,334,057 | 16,670,285 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -8,527 | -42,635 | -144,959 | -196,121 | -724,795 | -980,605 | -3,334,057 | -16,670,285 |
