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 42,010,133, 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 | 42,010,133 | |
| -1 | -42,010,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,010,133.
Example:
1 x 42,010,133 = 42,010,133
and
-1 x -42,010,133 = 42,010,133
Notice both answers equal 42,010,133
With that explanation out of the way, let's continue. Next, we take the number 42,010,133 and divide it by 2:
42,010,133 ÷ 2 = 21,005,066.5
If the quotient is a whole number, then 2 and 21,005,066.5 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 | 42,010,133 | |
| -1 | -42,010,133 |
Now, we try dividing 42,010,133 by 3:
42,010,133 ÷ 3 = 14,003,377.6667
If the quotient is a whole number, then 3 and 14,003,377.6667 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 | 42,010,133 | |
| -1 | -42,010,133 |
Let's try dividing by 4:
42,010,133 ÷ 4 = 10,502,533.25
If the quotient is a whole number, then 4 and 10,502,533.25 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 | 42,010,133 | |
| -1 | 42,010,133 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 233 | 407 | 443 | 2,563 | 4,873 | 8,621 | 16,391 | 94,831 | 103,219 | 180,301 | 1,135,409 | 3,819,103 | 42,010,133 |
| -1 | -11 | -37 | -233 | -407 | -443 | -2,563 | -4,873 | -8,621 | -16,391 | -94,831 | -103,219 | -180,301 | -1,135,409 | -3,819,103 | -42,010,133 |
