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 124,215,445, 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 | 124,215,445 | |
| -1 | -124,215,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,215,445.
Example:
1 x 124,215,445 = 124,215,445
and
-1 x -124,215,445 = 124,215,445
Notice both answers equal 124,215,445
With that explanation out of the way, let's continue. Next, we take the number 124,215,445 and divide it by 2:
124,215,445 ÷ 2 = 62,107,722.5
If the quotient is a whole number, then 2 and 62,107,722.5 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 | 124,215,445 | |
| -1 | -124,215,445 |
Now, we try dividing 124,215,445 by 3:
124,215,445 ÷ 3 = 41,405,148.3333
If the quotient is a whole number, then 3 and 41,405,148.3333 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 | 124,215,445 | |
| -1 | -124,215,445 |
Let's try dividing by 4:
124,215,445 ÷ 4 = 31,053,861.25
If the quotient is a whole number, then 4 and 31,053,861.25 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 | 124,215,445 | |
| -1 | 124,215,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 3,895 | 31,891 | 159,455 | 605,929 | 1,307,531 | 3,029,645 | 6,537,655 | 24,843,089 | 124,215,445 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -3,895 | -31,891 | -159,455 | -605,929 | -1,307,531 | -3,029,645 | -6,537,655 | -24,843,089 | -124,215,445 |
