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 134,311,073, 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 | 134,311,073 | |
| -1 | -134,311,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,311,073.
Example:
1 x 134,311,073 = 134,311,073
and
-1 x -134,311,073 = 134,311,073
Notice both answers equal 134,311,073
With that explanation out of the way, let's continue. Next, we take the number 134,311,073 and divide it by 2:
134,311,073 ÷ 2 = 67,155,536.5
If the quotient is a whole number, then 2 and 67,155,536.5 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 | 134,311,073 | |
| -1 | -134,311,073 |
Now, we try dividing 134,311,073 by 3:
134,311,073 ÷ 3 = 44,770,357.6667
If the quotient is a whole number, then 3 and 44,770,357.6667 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 | 134,311,073 | |
| -1 | -134,311,073 |
Let's try dividing by 4:
134,311,073 ÷ 4 = 33,577,768.25
If the quotient is a whole number, then 4 and 33,577,768.25 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 | 134,311,073 | |
| -1 | 134,311,073 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 103 | 481 | 1,339 | 2,711 | 3,811 | 35,243 | 49,543 | 100,307 | 279,233 | 1,303,991 | 3,630,029 | 10,331,621 | 134,311,073 |
| -1 | -13 | -37 | -103 | -481 | -1,339 | -2,711 | -3,811 | -35,243 | -49,543 | -100,307 | -279,233 | -1,303,991 | -3,630,029 | -10,331,621 | -134,311,073 |
