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 123,052,171, 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 | 123,052,171 | |
| -1 | -123,052,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,052,171.
Example:
1 x 123,052,171 = 123,052,171
and
-1 x -123,052,171 = 123,052,171
Notice both answers equal 123,052,171
With that explanation out of the way, let's continue. Next, we take the number 123,052,171 and divide it by 2:
123,052,171 ÷ 2 = 61,526,085.5
If the quotient is a whole number, then 2 and 61,526,085.5 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 | 123,052,171 | |
| -1 | -123,052,171 |
Now, we try dividing 123,052,171 by 3:
123,052,171 ÷ 3 = 41,017,390.3333
If the quotient is a whole number, then 3 and 41,017,390.3333 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 | 123,052,171 | |
| -1 | -123,052,171 |
Let's try dividing by 4:
123,052,171 ÷ 4 = 30,763,042.75
If the quotient is a whole number, then 4 and 30,763,042.75 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 | 123,052,171 | |
| -1 | 123,052,171 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 109 | 187 | 1,199 | 1,853 | 6,037 | 20,383 | 66,407 | 102,629 | 658,033 | 1,128,919 | 7,238,363 | 11,186,561 | 123,052,171 |
| -1 | -11 | -17 | -109 | -187 | -1,199 | -1,853 | -6,037 | -20,383 | -66,407 | -102,629 | -658,033 | -1,128,919 | -7,238,363 | -11,186,561 | -123,052,171 |
