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 124,052,101, 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 | 124,052,101 | |
| -1 | -124,052,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,052,101.
Example:
1 x 124,052,101 = 124,052,101
and
-1 x -124,052,101 = 124,052,101
Notice both answers equal 124,052,101
With that explanation out of the way, let's continue. Next, we take the number 124,052,101 and divide it by 2:
124,052,101 ÷ 2 = 62,026,050.5
If the quotient is a whole number, then 2 and 62,026,050.5 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 | 124,052,101 | |
| -1 | -124,052,101 |
Now, we try dividing 124,052,101 by 3:
124,052,101 ÷ 3 = 41,350,700.3333
If the quotient is a whole number, then 3 and 41,350,700.3333 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 | 124,052,101 | |
| -1 | -124,052,101 |
Let's try dividing by 4:
124,052,101 ÷ 4 = 31,013,025.25
If the quotient is a whole number, then 4 and 31,013,025.25 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 | 124,052,101 | |
| -1 | 124,052,101 |
If you did it right, you will end up with this table:
| 1 | 41 | 61 | 193 | 257 | 2,501 | 7,913 | 10,537 | 11,773 | 15,677 | 49,601 | 482,693 | 642,757 | 2,033,641 | 3,025,661 | 124,052,101 |
| -1 | -41 | -61 | -193 | -257 | -2,501 | -7,913 | -10,537 | -11,773 | -15,677 | -49,601 | -482,693 | -642,757 | -2,033,641 | -3,025,661 | -124,052,101 |
