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 123,334,541, 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 | 123,334,541 | |
| -1 | -123,334,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,334,541.
Example:
1 x 123,334,541 = 123,334,541
and
-1 x -123,334,541 = 123,334,541
Notice both answers equal 123,334,541
With that explanation out of the way, let's continue. Next, we take the number 123,334,541 and divide it by 2:
123,334,541 ÷ 2 = 61,667,270.5
If the quotient is a whole number, then 2 and 61,667,270.5 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 | 123,334,541 | |
| -1 | -123,334,541 |
Now, we try dividing 123,334,541 by 3:
123,334,541 ÷ 3 = 41,111,513.6667
If the quotient is a whole number, then 3 and 41,111,513.6667 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 | 123,334,541 | |
| -1 | -123,334,541 |
Let's try dividing by 4:
123,334,541 ÷ 4 = 30,833,635.25
If the quotient is a whole number, then 4 and 30,833,635.25 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 | 123,334,541 | |
| -1 | 123,334,541 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 293 | 2,251 | 3,223 | 4,981 | 24,761 | 38,267 | 54,791 | 420,937 | 659,543 | 7,254,973 | 11,212,231 | 123,334,541 |
| -1 | -11 | -17 | -187 | -293 | -2,251 | -3,223 | -4,981 | -24,761 | -38,267 | -54,791 | -420,937 | -659,543 | -7,254,973 | -11,212,231 | -123,334,541 |
