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 16,241,143, 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 | 16,241,143 | |
| -1 | -16,241,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,241,143.
Example:
1 x 16,241,143 = 16,241,143
and
-1 x -16,241,143 = 16,241,143
Notice both answers equal 16,241,143
With that explanation out of the way, let's continue. Next, we take the number 16,241,143 and divide it by 2:
16,241,143 ÷ 2 = 8,120,571.5
If the quotient is a whole number, then 2 and 8,120,571.5 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 | 16,241,143 | |
| -1 | -16,241,143 |
Now, we try dividing 16,241,143 by 3:
16,241,143 ÷ 3 = 5,413,714.3333
If the quotient is a whole number, then 3 and 5,413,714.3333 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 | 16,241,143 | |
| -1 | -16,241,143 |
Let's try dividing by 4:
16,241,143 ÷ 4 = 4,060,285.75
If the quotient is a whole number, then 4 and 4,060,285.75 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 | 16,241,143 | |
| -1 | 16,241,143 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 103 | 193 | 817 | 1,957 | 3,667 | 4,429 | 8,299 | 19,879 | 84,151 | 157,681 | 377,701 | 854,797 | 16,241,143 |
| -1 | -19 | -43 | -103 | -193 | -817 | -1,957 | -3,667 | -4,429 | -8,299 | -19,879 | -84,151 | -157,681 | -377,701 | -854,797 | -16,241,143 |
