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 134,423,201, 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 | 134,423,201 | |
| -1 | -134,423,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,423,201.
Example:
1 x 134,423,201 = 134,423,201
and
-1 x -134,423,201 = 134,423,201
Notice both answers equal 134,423,201
With that explanation out of the way, let's continue. Next, we take the number 134,423,201 and divide it by 2:
134,423,201 ÷ 2 = 67,211,600.5
If the quotient is a whole number, then 2 and 67,211,600.5 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 | 134,423,201 | |
| -1 | -134,423,201 |
Now, we try dividing 134,423,201 by 3:
134,423,201 ÷ 3 = 44,807,733.6667
If the quotient is a whole number, then 3 and 44,807,733.6667 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 | 134,423,201 | |
| -1 | -134,423,201 |
Let's try dividing by 4:
134,423,201 ÷ 4 = 33,605,800.25
If the quotient is a whole number, then 4 and 33,605,800.25 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 | 134,423,201 | |
| -1 | 134,423,201 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 487 | 1,091 | 5,357 | 11,201 | 12,001 | 25,093 | 123,211 | 276,023 | 531,317 | 5,844,487 | 12,220,291 | 134,423,201 |
| -1 | -11 | -23 | -253 | -487 | -1,091 | -5,357 | -11,201 | -12,001 | -25,093 | -123,211 | -276,023 | -531,317 | -5,844,487 | -12,220,291 | -134,423,201 |
