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 42,032,335, 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 | 42,032,335 | |
| -1 | -42,032,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,032,335.
Example:
1 x 42,032,335 = 42,032,335
and
-1 x -42,032,335 = 42,032,335
Notice both answers equal 42,032,335
With that explanation out of the way, let's continue. Next, we take the number 42,032,335 and divide it by 2:
42,032,335 ÷ 2 = 21,016,167.5
If the quotient is a whole number, then 2 and 21,016,167.5 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 | 42,032,335 | |
| -1 | -42,032,335 |
Now, we try dividing 42,032,335 by 3:
42,032,335 ÷ 3 = 14,010,778.3333
If the quotient is a whole number, then 3 and 14,010,778.3333 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 | 42,032,335 | |
| -1 | -42,032,335 |
Let's try dividing by 4:
42,032,335 ÷ 4 = 10,508,083.75
If the quotient is a whole number, then 4 and 10,508,083.75 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 | 42,032,335 | |
| -1 | 42,032,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 383 | 467 | 1,915 | 2,335 | 18,001 | 21,949 | 90,005 | 109,745 | 178,861 | 894,305 | 8,406,467 | 42,032,335 |
| -1 | -5 | -47 | -235 | -383 | -467 | -1,915 | -2,335 | -18,001 | -21,949 | -90,005 | -109,745 | -178,861 | -894,305 | -8,406,467 | -42,032,335 |
