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 124,224,503, 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 | 124,224,503 | |
| -1 | -124,224,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,224,503.
Example:
1 x 124,224,503 = 124,224,503
and
-1 x -124,224,503 = 124,224,503
Notice both answers equal 124,224,503
With that explanation out of the way, let's continue. Next, we take the number 124,224,503 and divide it by 2:
124,224,503 ÷ 2 = 62,112,251.5
If the quotient is a whole number, then 2 and 62,112,251.5 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 | 124,224,503 | |
| -1 | -124,224,503 |
Now, we try dividing 124,224,503 by 3:
124,224,503 ÷ 3 = 41,408,167.6667
If the quotient is a whole number, then 3 and 41,408,167.6667 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 | 124,224,503 | |
| -1 | -124,224,503 |
Let's try dividing by 4:
124,224,503 ÷ 4 = 31,056,125.75
If the quotient is a whole number, then 4 and 31,056,125.75 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 | 124,224,503 | |
| -1 | 124,224,503 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 271 | 481 | 953 | 3,523 | 10,027 | 12,389 | 35,261 | 130,351 | 258,263 | 458,393 | 3,357,419 | 9,555,731 | 124,224,503 |
| -1 | -13 | -37 | -271 | -481 | -953 | -3,523 | -10,027 | -12,389 | -35,261 | -130,351 | -258,263 | -458,393 | -3,357,419 | -9,555,731 | -124,224,503 |
