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 124,224,055, 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 | 124,224,055 | |
| -1 | -124,224,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,224,055.
Example:
1 x 124,224,055 = 124,224,055
and
-1 x -124,224,055 = 124,224,055
Notice both answers equal 124,224,055
With that explanation out of the way, let's continue. Next, we take the number 124,224,055 and divide it by 2:
124,224,055 ÷ 2 = 62,112,027.5
If the quotient is a whole number, then 2 and 62,112,027.5 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 | 124,224,055 | |
| -1 | -124,224,055 |
Now, we try dividing 124,224,055 by 3:
124,224,055 ÷ 3 = 41,408,018.3333
If the quotient is a whole number, then 3 and 41,408,018.3333 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 | 124,224,055 | |
| -1 | -124,224,055 |
Let's try dividing by 4:
124,224,055 ÷ 4 = 31,056,013.75
If the quotient is a whole number, then 4 and 31,056,013.75 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 | 124,224,055 | |
| -1 | 124,224,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 47 | 205 | 235 | 1,927 | 9,635 | 12,893 | 64,465 | 528,613 | 605,971 | 2,643,065 | 3,029,855 | 24,844,811 | 124,224,055 |
| -1 | -5 | -41 | -47 | -205 | -235 | -1,927 | -9,635 | -12,893 | -64,465 | -528,613 | -605,971 | -2,643,065 | -3,029,855 | -24,844,811 | -124,224,055 |
