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 124,002,043, 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 | 124,002,043 | |
| -1 | -124,002,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,002,043.
Example:
1 x 124,002,043 = 124,002,043
and
-1 x -124,002,043 = 124,002,043
Notice both answers equal 124,002,043
With that explanation out of the way, let's continue. Next, we take the number 124,002,043 and divide it by 2:
124,002,043 ÷ 2 = 62,001,021.5
If the quotient is a whole number, then 2 and 62,001,021.5 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 | 124,002,043 | |
| -1 | -124,002,043 |
Now, we try dividing 124,002,043 by 3:
124,002,043 ÷ 3 = 41,334,014.3333
If the quotient is a whole number, then 3 and 41,334,014.3333 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 | 124,002,043 | |
| -1 | -124,002,043 |
Let's try dividing by 4:
124,002,043 ÷ 4 = 31,000,510.75
If the quotient is a whole number, then 4 and 31,000,510.75 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 | 124,002,043 | |
| -1 | 124,002,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 239 | 467 | 1,111 | 2,629 | 5,137 | 24,139 | 47,167 | 111,613 | 265,529 | 518,837 | 1,227,743 | 11,272,913 | 124,002,043 |
| -1 | -11 | -101 | -239 | -467 | -1,111 | -2,629 | -5,137 | -24,139 | -47,167 | -111,613 | -265,529 | -518,837 | -1,227,743 | -11,272,913 | -124,002,043 |
