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 42,256,123, 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 | 42,256,123 | |
| -1 | -42,256,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,256,123.
Example:
1 x 42,256,123 = 42,256,123
and
-1 x -42,256,123 = 42,256,123
Notice both answers equal 42,256,123
With that explanation out of the way, let's continue. Next, we take the number 42,256,123 and divide it by 2:
42,256,123 ÷ 2 = 21,128,061.5
If the quotient is a whole number, then 2 and 21,128,061.5 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 | 42,256,123 | |
| -1 | -42,256,123 |
Now, we try dividing 42,256,123 by 3:
42,256,123 ÷ 3 = 14,085,374.3333
If the quotient is a whole number, then 3 and 14,085,374.3333 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 | 42,256,123 | |
| -1 | -42,256,123 |
Let's try dividing by 4:
42,256,123 ÷ 4 = 10,564,030.75
If the quotient is a whole number, then 4 and 10,564,030.75 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 | 42,256,123 | |
| -1 | 42,256,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 511 | 949 | 6,361 | 6,643 | 44,527 | 82,693 | 464,353 | 578,851 | 3,250,471 | 6,036,589 | 42,256,123 |
| -1 | -7 | -13 | -73 | -91 | -511 | -949 | -6,361 | -6,643 | -44,527 | -82,693 | -464,353 | -578,851 | -3,250,471 | -6,036,589 | -42,256,123 |
