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 42,404,065, 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 | 42,404,065 | |
| -1 | -42,404,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,404,065.
Example:
1 x 42,404,065 = 42,404,065
and
-1 x -42,404,065 = 42,404,065
Notice both answers equal 42,404,065
With that explanation out of the way, let's continue. Next, we take the number 42,404,065 and divide it by 2:
42,404,065 ÷ 2 = 21,202,032.5
If the quotient is a whole number, then 2 and 21,202,032.5 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 | 42,404,065 | |
| -1 | -42,404,065 |
Now, we try dividing 42,404,065 by 3:
42,404,065 ÷ 3 = 14,134,688.3333
If the quotient is a whole number, then 3 and 14,134,688.3333 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 | 42,404,065 | |
| -1 | -42,404,065 |
Let's try dividing by 4:
42,404,065 ÷ 4 = 10,601,016.25
If the quotient is a whole number, then 4 and 10,601,016.25 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 | 42,404,065 | |
| -1 | 42,404,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 33,521 | 167,605 | 368,731 | 770,983 | 1,843,655 | 3,854,915 | 8,480,813 | 42,404,065 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -33,521 | -167,605 | -368,731 | -770,983 | -1,843,655 | -3,854,915 | -8,480,813 | -42,404,065 |
