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 134,050,741, 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 | 134,050,741 | |
| -1 | -134,050,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,050,741.
Example:
1 x 134,050,741 = 134,050,741
and
-1 x -134,050,741 = 134,050,741
Notice both answers equal 134,050,741
With that explanation out of the way, let's continue. Next, we take the number 134,050,741 and divide it by 2:
134,050,741 ÷ 2 = 67,025,370.5
If the quotient is a whole number, then 2 and 67,025,370.5 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 | 134,050,741 | |
| -1 | -134,050,741 |
Now, we try dividing 134,050,741 by 3:
134,050,741 ÷ 3 = 44,683,580.3333
If the quotient is a whole number, then 3 and 44,683,580.3333 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 | 134,050,741 | |
| -1 | -134,050,741 |
Let's try dividing by 4:
134,050,741 ÷ 4 = 33,512,685.25
If the quotient is a whole number, then 4 and 33,512,685.25 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 | 134,050,741 | |
| -1 | 134,050,741 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 317 | 407 | 1,039 | 3,487 | 11,429 | 11,729 | 38,443 | 129,019 | 329,363 | 422,873 | 3,622,993 | 12,186,431 | 134,050,741 |
| -1 | -11 | -37 | -317 | -407 | -1,039 | -3,487 | -11,429 | -11,729 | -38,443 | -129,019 | -329,363 | -422,873 | -3,622,993 | -12,186,431 | -134,050,741 |
