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 134,644,235, 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 | 134,644,235 | |
| -1 | -134,644,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,644,235.
Example:
1 x 134,644,235 = 134,644,235
and
-1 x -134,644,235 = 134,644,235
Notice both answers equal 134,644,235
With that explanation out of the way, let's continue. Next, we take the number 134,644,235 and divide it by 2:
134,644,235 ÷ 2 = 67,322,117.5
If the quotient is a whole number, then 2 and 67,322,117.5 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 | 134,644,235 | |
| -1 | -134,644,235 |
Now, we try dividing 134,644,235 by 3:
134,644,235 ÷ 3 = 44,881,411.6667
If the quotient is a whole number, then 3 and 44,881,411.6667 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 | 134,644,235 | |
| -1 | -134,644,235 |
Let's try dividing by 4:
134,644,235 ÷ 4 = 33,661,058.75
If the quotient is a whole number, then 4 and 33,661,058.75 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 | 134,644,235 | |
| -1 | 134,644,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 239 | 1,195 | 2,629 | 10,243 | 13,145 | 51,215 | 112,673 | 563,365 | 2,448,077 | 12,240,385 | 26,928,847 | 134,644,235 |
| -1 | -5 | -11 | -55 | -239 | -1,195 | -2,629 | -10,243 | -13,145 | -51,215 | -112,673 | -563,365 | -2,448,077 | -12,240,385 | -26,928,847 | -134,644,235 |
