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 134,460,431, 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 | 134,460,431 | |
| -1 | -134,460,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,460,431.
Example:
1 x 134,460,431 = 134,460,431
and
-1 x -134,460,431 = 134,460,431
Notice both answers equal 134,460,431
With that explanation out of the way, let's continue. Next, we take the number 134,460,431 and divide it by 2:
134,460,431 ÷ 2 = 67,230,215.5
If the quotient is a whole number, then 2 and 67,230,215.5 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 | 134,460,431 | |
| -1 | -134,460,431 |
Now, we try dividing 134,460,431 by 3:
134,460,431 ÷ 3 = 44,820,143.6667
If the quotient is a whole number, then 3 and 44,820,143.6667 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 | 134,460,431 | |
| -1 | -134,460,431 |
Let's try dividing by 4:
134,460,431 ÷ 4 = 33,615,107.75
If the quotient is a whole number, then 4 and 33,615,107.75 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 | 134,460,431 | |
| -1 | 134,460,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 149 | 941 | 959 | 1,043 | 6,587 | 20,413 | 128,917 | 140,209 | 142,891 | 902,419 | 981,463 | 19,208,633 | 134,460,431 |
| -1 | -7 | -137 | -149 | -941 | -959 | -1,043 | -6,587 | -20,413 | -128,917 | -140,209 | -142,891 | -902,419 | -981,463 | -19,208,633 | -134,460,431 |
