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 124,003,523, 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 | 124,003,523 | |
| -1 | -124,003,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,003,523.
Example:
1 x 124,003,523 = 124,003,523
and
-1 x -124,003,523 = 124,003,523
Notice both answers equal 124,003,523
With that explanation out of the way, let's continue. Next, we take the number 124,003,523 and divide it by 2:
124,003,523 ÷ 2 = 62,001,761.5
If the quotient is a whole number, then 2 and 62,001,761.5 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 | 124,003,523 | |
| -1 | -124,003,523 |
Now, we try dividing 124,003,523 by 3:
124,003,523 ÷ 3 = 41,334,507.6667
If the quotient is a whole number, then 3 and 41,334,507.6667 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 | 124,003,523 | |
| -1 | -124,003,523 |
Let's try dividing by 4:
124,003,523 ÷ 4 = 31,000,880.75
If the quotient is a whole number, then 4 and 31,000,880.75 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 | 124,003,523 | |
| -1 | 124,003,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 331 | 491 | 763 | 2,317 | 3,437 | 36,079 | 53,519 | 162,521 | 252,553 | 374,633 | 1,137,647 | 17,714,789 | 124,003,523 |
| -1 | -7 | -109 | -331 | -491 | -763 | -2,317 | -3,437 | -36,079 | -53,519 | -162,521 | -252,553 | -374,633 | -1,137,647 | -17,714,789 | -124,003,523 |
