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 137,776,717, 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 | 137,776,717 | |
| -1 | -137,776,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,776,717.
Example:
1 x 137,776,717 = 137,776,717
and
-1 x -137,776,717 = 137,776,717
Notice both answers equal 137,776,717
With that explanation out of the way, let's continue. Next, we take the number 137,776,717 and divide it by 2:
137,776,717 ÷ 2 = 68,888,358.5
If the quotient is a whole number, then 2 and 68,888,358.5 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 | 137,776,717 | |
| -1 | -137,776,717 |
Now, we try dividing 137,776,717 by 3:
137,776,717 ÷ 3 = 45,925,572.3333
If the quotient is a whole number, then 3 and 45,925,572.3333 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 | 137,776,717 | |
| -1 | -137,776,717 |
Let's try dividing by 4:
137,776,717 ÷ 4 = 34,444,179.25
If the quotient is a whole number, then 4 and 34,444,179.25 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 | 137,776,717 | |
| -1 | 137,776,717 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 193 | 617 | 1,157 | 2,509 | 8,021 | 17,177 | 54,913 | 119,081 | 223,301 | 713,869 | 1,548,053 | 10,598,209 | 137,776,717 |
| -1 | -13 | -89 | -193 | -617 | -1,157 | -2,509 | -8,021 | -17,177 | -54,913 | -119,081 | -223,301 | -713,869 | -1,548,053 | -10,598,209 | -137,776,717 |
