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 16,060,457, 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 | 16,060,457 | |
| -1 | -16,060,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,060,457.
Example:
1 x 16,060,457 = 16,060,457
and
-1 x -16,060,457 = 16,060,457
Notice both answers equal 16,060,457
With that explanation out of the way, let's continue. Next, we take the number 16,060,457 and divide it by 2:
16,060,457 ÷ 2 = 8,030,228.5
If the quotient is a whole number, then 2 and 8,030,228.5 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 | 16,060,457 | |
| -1 | -16,060,457 |
Now, we try dividing 16,060,457 by 3:
16,060,457 ÷ 3 = 5,353,485.6667
If the quotient is a whole number, then 3 and 5,353,485.6667 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 | 16,060,457 | |
| -1 | -16,060,457 |
Let's try dividing by 4:
16,060,457 ÷ 4 = 4,015,114.25
If the quotient is a whole number, then 4 and 4,015,114.25 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 | 16,060,457 | |
| -1 | 16,060,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 229 | 233 | 301 | 1,603 | 1,631 | 9,847 | 10,019 | 53,357 | 68,929 | 70,133 | 373,499 | 2,294,351 | 16,060,457 |
| -1 | -7 | -43 | -229 | -233 | -301 | -1,603 | -1,631 | -9,847 | -10,019 | -53,357 | -68,929 | -70,133 | -373,499 | -2,294,351 | -16,060,457 |
