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 42,024,109, 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 | 42,024,109 | |
| -1 | -42,024,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,024,109.
Example:
1 x 42,024,109 = 42,024,109
and
-1 x -42,024,109 = 42,024,109
Notice both answers equal 42,024,109
With that explanation out of the way, let's continue. Next, we take the number 42,024,109 and divide it by 2:
42,024,109 ÷ 2 = 21,012,054.5
If the quotient is a whole number, then 2 and 21,012,054.5 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 | 42,024,109 | |
| -1 | -42,024,109 |
Now, we try dividing 42,024,109 by 3:
42,024,109 ÷ 3 = 14,008,036.3333
If the quotient is a whole number, then 3 and 14,008,036.3333 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 | 42,024,109 | |
| -1 | -42,024,109 |
Let's try dividing by 4:
42,024,109 ÷ 4 = 10,506,027.25
If the quotient is a whole number, then 4 and 10,506,027.25 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 | 42,024,109 | |
| -1 | 42,024,109 |
If you did it right, you will end up with this table:
| 1 | 89 | 149 | 3,169 | 13,261 | 282,041 | 472,181 | 42,024,109 |
| -1 | -89 | -149 | -3,169 | -13,261 | -282,041 | -472,181 | -42,024,109 |
