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 42,341,233, 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 | 42,341,233 | |
| -1 | -42,341,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,341,233.
Example:
1 x 42,341,233 = 42,341,233
and
-1 x -42,341,233 = 42,341,233
Notice both answers equal 42,341,233
With that explanation out of the way, let's continue. Next, we take the number 42,341,233 and divide it by 2:
42,341,233 ÷ 2 = 21,170,616.5
If the quotient is a whole number, then 2 and 21,170,616.5 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 | 42,341,233 | |
| -1 | -42,341,233 |
Now, we try dividing 42,341,233 by 3:
42,341,233 ÷ 3 = 14,113,744.3333
If the quotient is a whole number, then 3 and 14,113,744.3333 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 | 42,341,233 | |
| -1 | -42,341,233 |
Let's try dividing by 4:
42,341,233 ÷ 4 = 10,585,308.25
If the quotient is a whole number, then 4 and 10,585,308.25 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 | 42,341,233 | |
| -1 | 42,341,233 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 223 | 421 | 451 | 2,453 | 4,631 | 9,143 | 17,261 | 93,883 | 100,573 | 189,871 | 1,032,713 | 3,849,203 | 42,341,233 |
| -1 | -11 | -41 | -223 | -421 | -451 | -2,453 | -4,631 | -9,143 | -17,261 | -93,883 | -100,573 | -189,871 | -1,032,713 | -3,849,203 | -42,341,233 |
