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 137,857,055, 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 | 137,857,055 | |
| -1 | -137,857,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,857,055.
Example:
1 x 137,857,055 = 137,857,055
and
-1 x -137,857,055 = 137,857,055
Notice both answers equal 137,857,055
With that explanation out of the way, let's continue. Next, we take the number 137,857,055 and divide it by 2:
137,857,055 ÷ 2 = 68,928,527.5
If the quotient is a whole number, then 2 and 68,928,527.5 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 | 137,857,055 | |
| -1 | -137,857,055 |
Now, we try dividing 137,857,055 by 3:
137,857,055 ÷ 3 = 45,952,351.6667
If the quotient is a whole number, then 3 and 45,952,351.6667 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 | 137,857,055 | |
| -1 | -137,857,055 |
Let's try dividing by 4:
137,857,055 ÷ 4 = 34,464,263.75
If the quotient is a whole number, then 4 and 34,464,263.75 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 | 137,857,055 | |
| -1 | 137,857,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 171,251 | 856,255 | 1,198,757 | 3,938,773 | 5,993,785 | 19,693,865 | 27,571,411 | 137,857,055 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -171,251 | -856,255 | -1,198,757 | -3,938,773 | -5,993,785 | -19,693,865 | -27,571,411 | -137,857,055 |
