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 137,451,755, 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 | 137,451,755 | |
| -1 | -137,451,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,451,755.
Example:
1 x 137,451,755 = 137,451,755
and
-1 x -137,451,755 = 137,451,755
Notice both answers equal 137,451,755
With that explanation out of the way, let's continue. Next, we take the number 137,451,755 and divide it by 2:
137,451,755 ÷ 2 = 68,725,877.5
If the quotient is a whole number, then 2 and 68,725,877.5 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 | 137,451,755 | |
| -1 | -137,451,755 |
Now, we try dividing 137,451,755 by 3:
137,451,755 ÷ 3 = 45,817,251.6667
If the quotient is a whole number, then 3 and 45,817,251.6667 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 | 137,451,755 | |
| -1 | -137,451,755 |
Let's try dividing by 4:
137,451,755 ÷ 4 = 34,362,938.75
If the quotient is a whole number, then 4 and 34,362,938.75 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 | 137,451,755 | |
| -1 | 137,451,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 149 | 745 | 1,043 | 5,215 | 26,357 | 131,785 | 184,499 | 922,495 | 3,927,193 | 19,635,965 | 27,490,351 | 137,451,755 |
| -1 | -5 | -7 | -35 | -149 | -745 | -1,043 | -5,215 | -26,357 | -131,785 | -184,499 | -922,495 | -3,927,193 | -19,635,965 | -27,490,351 | -137,451,755 |
