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 134,551,105, 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 | 134,551,105 | |
| -1 | -134,551,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,551,105.
Example:
1 x 134,551,105 = 134,551,105
and
-1 x -134,551,105 = 134,551,105
Notice both answers equal 134,551,105
With that explanation out of the way, let's continue. Next, we take the number 134,551,105 and divide it by 2:
134,551,105 ÷ 2 = 67,275,552.5
If the quotient is a whole number, then 2 and 67,275,552.5 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 | 134,551,105 | |
| -1 | -134,551,105 |
Now, we try dividing 134,551,105 by 3:
134,551,105 ÷ 3 = 44,850,368.3333
If the quotient is a whole number, then 3 and 44,850,368.3333 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 | 134,551,105 | |
| -1 | -134,551,105 |
Let's try dividing by 4:
134,551,105 ÷ 4 = 33,637,776.25
If the quotient is a whole number, then 4 and 33,637,776.25 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 | 134,551,105 | |
| -1 | 134,551,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,277 | 1,621 | 6,385 | 8,105 | 16,601 | 21,073 | 83,005 | 105,365 | 2,070,017 | 10,350,085 | 26,910,221 | 134,551,105 |
| -1 | -5 | -13 | -65 | -1,277 | -1,621 | -6,385 | -8,105 | -16,601 | -21,073 | -83,005 | -105,365 | -2,070,017 | -10,350,085 | -26,910,221 | -134,551,105 |
