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 124,271,329, 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 | 124,271,329 | |
| -1 | -124,271,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,271,329.
Example:
1 x 124,271,329 = 124,271,329
and
-1 x -124,271,329 = 124,271,329
Notice both answers equal 124,271,329
With that explanation out of the way, let's continue. Next, we take the number 124,271,329 and divide it by 2:
124,271,329 ÷ 2 = 62,135,664.5
If the quotient is a whole number, then 2 and 62,135,664.5 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 | 124,271,329 | |
| -1 | -124,271,329 |
Now, we try dividing 124,271,329 by 3:
124,271,329 ÷ 3 = 41,423,776.3333
If the quotient is a whole number, then 3 and 41,423,776.3333 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 | 124,271,329 | |
| -1 | -124,271,329 |
Let's try dividing by 4:
124,271,329 ÷ 4 = 31,067,832.25
If the quotient is a whole number, then 4 and 31,067,832.25 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 | 124,271,329 | |
| -1 | 124,271,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 313 | 2,191 | 4,069 | 4,363 | 28,483 | 30,541 | 56,719 | 397,033 | 1,365,619 | 9,559,333 | 17,753,047 | 124,271,329 |
| -1 | -7 | -13 | -91 | -313 | -2,191 | -4,069 | -4,363 | -28,483 | -30,541 | -56,719 | -397,033 | -1,365,619 | -9,559,333 | -17,753,047 | -124,271,329 |
