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 124,345,235, 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 | 124,345,235 | |
| -1 | -124,345,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,345,235.
Example:
1 x 124,345,235 = 124,345,235
and
-1 x -124,345,235 = 124,345,235
Notice both answers equal 124,345,235
With that explanation out of the way, let's continue. Next, we take the number 124,345,235 and divide it by 2:
124,345,235 ÷ 2 = 62,172,617.5
If the quotient is a whole number, then 2 and 62,172,617.5 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 | 124,345,235 | |
| -1 | -124,345,235 |
Now, we try dividing 124,345,235 by 3:
124,345,235 ÷ 3 = 41,448,411.6667
If the quotient is a whole number, then 3 and 41,448,411.6667 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 | 124,345,235 | |
| -1 | -124,345,235 |
Let's try dividing by 4:
124,345,235 ÷ 4 = 31,086,308.75
If the quotient is a whole number, then 4 and 31,086,308.75 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 | 124,345,235 | |
| -1 | 124,345,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 535 | 749 | 3,745 | 33,203 | 166,015 | 232,421 | 1,162,105 | 3,552,721 | 17,763,605 | 24,869,047 | 124,345,235 |
| -1 | -5 | -7 | -35 | -107 | -535 | -749 | -3,745 | -33,203 | -166,015 | -232,421 | -1,162,105 | -3,552,721 | -17,763,605 | -24,869,047 | -124,345,235 |
