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 134,047,115, 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 | 134,047,115 | |
| -1 | -134,047,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,047,115.
Example:
1 x 134,047,115 = 134,047,115
and
-1 x -134,047,115 = 134,047,115
Notice both answers equal 134,047,115
With that explanation out of the way, let's continue. Next, we take the number 134,047,115 and divide it by 2:
134,047,115 ÷ 2 = 67,023,557.5
If the quotient is a whole number, then 2 and 67,023,557.5 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 | 134,047,115 | |
| -1 | -134,047,115 |
Now, we try dividing 134,047,115 by 3:
134,047,115 ÷ 3 = 44,682,371.6667
If the quotient is a whole number, then 3 and 44,682,371.6667 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 | 134,047,115 | |
| -1 | -134,047,115 |
Let's try dividing by 4:
134,047,115 ÷ 4 = 33,511,778.75
If the quotient is a whole number, then 4 and 33,511,778.75 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 | 134,047,115 | |
| -1 | 134,047,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 59 | 185 | 295 | 2,183 | 10,915 | 12,281 | 61,405 | 454,397 | 724,579 | 2,271,985 | 3,622,895 | 26,809,423 | 134,047,115 |
| -1 | -5 | -37 | -59 | -185 | -295 | -2,183 | -10,915 | -12,281 | -61,405 | -454,397 | -724,579 | -2,271,985 | -3,622,895 | -26,809,423 | -134,047,115 |
