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 42,241,313, 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 | 42,241,313 | |
| -1 | -42,241,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,241,313.
Example:
1 x 42,241,313 = 42,241,313
and
-1 x -42,241,313 = 42,241,313
Notice both answers equal 42,241,313
With that explanation out of the way, let's continue. Next, we take the number 42,241,313 and divide it by 2:
42,241,313 ÷ 2 = 21,120,656.5
If the quotient is a whole number, then 2 and 21,120,656.5 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 | 42,241,313 | |
| -1 | -42,241,313 |
Now, we try dividing 42,241,313 by 3:
42,241,313 ÷ 3 = 14,080,437.6667
If the quotient is a whole number, then 3 and 14,080,437.6667 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 | 42,241,313 | |
| -1 | -42,241,313 |
Let's try dividing by 4:
42,241,313 ÷ 4 = 10,560,328.25
If the quotient is a whole number, then 4 and 10,560,328.25 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 | 42,241,313 | |
| -1 | 42,241,313 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 31 | 551 | 589 | 899 | 2,473 | 17,081 | 46,987 | 71,717 | 76,663 | 1,362,623 | 1,456,597 | 2,223,227 | 42,241,313 |
| -1 | -19 | -29 | -31 | -551 | -589 | -899 | -2,473 | -17,081 | -46,987 | -71,717 | -76,663 | -1,362,623 | -1,456,597 | -2,223,227 | -42,241,313 |
