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 134,202,131, 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 | 134,202,131 | |
| -1 | -134,202,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,202,131.
Example:
1 x 134,202,131 = 134,202,131
and
-1 x -134,202,131 = 134,202,131
Notice both answers equal 134,202,131
With that explanation out of the way, let's continue. Next, we take the number 134,202,131 and divide it by 2:
134,202,131 ÷ 2 = 67,101,065.5
If the quotient is a whole number, then 2 and 67,101,065.5 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 | 134,202,131 | |
| -1 | -134,202,131 |
Now, we try dividing 134,202,131 by 3:
134,202,131 ÷ 3 = 44,734,043.6667
If the quotient is a whole number, then 3 and 44,734,043.6667 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 | 134,202,131 | |
| -1 | -134,202,131 |
Let's try dividing by 4:
134,202,131 ÷ 4 = 33,550,532.75
If the quotient is a whole number, then 4 and 33,550,532.75 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 | 134,202,131 | |
| -1 | 134,202,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 49 | 119 | 217 | 527 | 833 | 1,519 | 3,689 | 5,197 | 25,823 | 36,379 | 88,349 | 161,107 | 254,653 | 618,443 | 1,127,749 | 2,738,819 | 4,329,101 | 7,894,243 | 19,171,733 | 134,202,131 |
| -1 | -7 | -17 | -31 | -49 | -119 | -217 | -527 | -833 | -1,519 | -3,689 | -5,197 | -25,823 | -36,379 | -88,349 | -161,107 | -254,653 | -618,443 | -1,127,749 | -2,738,819 | -4,329,101 | -7,894,243 | -19,171,733 | -134,202,131 |
