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 16,025,713, 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 | 16,025,713 | |
| -1 | -16,025,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,025,713.
Example:
1 x 16,025,713 = 16,025,713
and
-1 x -16,025,713 = 16,025,713
Notice both answers equal 16,025,713
With that explanation out of the way, let's continue. Next, we take the number 16,025,713 and divide it by 2:
16,025,713 ÷ 2 = 8,012,856.5
If the quotient is a whole number, then 2 and 8,012,856.5 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 | 16,025,713 | |
| -1 | -16,025,713 |
Now, we try dividing 16,025,713 by 3:
16,025,713 ÷ 3 = 5,341,904.3333
If the quotient is a whole number, then 3 and 5,341,904.3333 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 | 16,025,713 | |
| -1 | -16,025,713 |
Let's try dividing by 4:
16,025,713 ÷ 4 = 4,006,428.25
If the quotient is a whole number, then 4 and 4,006,428.25 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 | 16,025,713 | |
| -1 | 16,025,713 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 43 | 187 | 473 | 731 | 1,993 | 8,041 | 21,923 | 33,881 | 85,699 | 372,691 | 942,689 | 1,456,883 | 16,025,713 |
| -1 | -11 | -17 | -43 | -187 | -473 | -731 | -1,993 | -8,041 | -21,923 | -33,881 | -85,699 | -372,691 | -942,689 | -1,456,883 | -16,025,713 |
