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 137,731,637, 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 | 137,731,637 | |
| -1 | -137,731,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,731,637.
Example:
1 x 137,731,637 = 137,731,637
and
-1 x -137,731,637 = 137,731,637
Notice both answers equal 137,731,637
With that explanation out of the way, let's continue. Next, we take the number 137,731,637 and divide it by 2:
137,731,637 ÷ 2 = 68,865,818.5
If the quotient is a whole number, then 2 and 68,865,818.5 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 | 137,731,637 | |
| -1 | -137,731,637 |
Now, we try dividing 137,731,637 by 3:
137,731,637 ÷ 3 = 45,910,545.6667
If the quotient is a whole number, then 3 and 45,910,545.6667 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 | 137,731,637 | |
| -1 | -137,731,637 |
Let's try dividing by 4:
137,731,637 ÷ 4 = 34,432,909.25
If the quotient is a whole number, then 4 and 34,432,909.25 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 | 137,731,637 | |
| -1 | 137,731,637 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 239 | 311 | 1,853 | 4,063 | 5,287 | 26,051 | 33,899 | 74,329 | 442,867 | 576,283 | 1,263,593 | 8,101,861 | 137,731,637 |
| -1 | -17 | -109 | -239 | -311 | -1,853 | -4,063 | -5,287 | -26,051 | -33,899 | -74,329 | -442,867 | -576,283 | -1,263,593 | -8,101,861 | -137,731,637 |
