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 124,123,241, 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 | 124,123,241 | |
| -1 | -124,123,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,123,241.
Example:
1 x 124,123,241 = 124,123,241
and
-1 x -124,123,241 = 124,123,241
Notice both answers equal 124,123,241
With that explanation out of the way, let's continue. Next, we take the number 124,123,241 and divide it by 2:
124,123,241 ÷ 2 = 62,061,620.5
If the quotient is a whole number, then 2 and 62,061,620.5 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 | 124,123,241 | |
| -1 | -124,123,241 |
Now, we try dividing 124,123,241 by 3:
124,123,241 ÷ 3 = 41,374,413.6667
If the quotient is a whole number, then 3 and 41,374,413.6667 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 | 124,123,241 | |
| -1 | -124,123,241 |
Let's try dividing by 4:
124,123,241 ÷ 4 = 31,030,810.25
If the quotient is a whole number, then 4 and 31,030,810.25 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 | 124,123,241 | |
| -1 | 124,123,241 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 397 | 473 | 661 | 4,367 | 7,271 | 17,071 | 28,423 | 187,781 | 262,417 | 312,653 | 2,886,587 | 11,283,931 | 124,123,241 |
| -1 | -11 | -43 | -397 | -473 | -661 | -4,367 | -7,271 | -17,071 | -28,423 | -187,781 | -262,417 | -312,653 | -2,886,587 | -11,283,931 | -124,123,241 |
