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 164,436,131, 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 | 164,436,131 | |
| -1 | -164,436,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,436,131.
Example:
1 x 164,436,131 = 164,436,131
and
-1 x -164,436,131 = 164,436,131
Notice both answers equal 164,436,131
With that explanation out of the way, let's continue. Next, we take the number 164,436,131 and divide it by 2:
164,436,131 ÷ 2 = 82,218,065.5
If the quotient is a whole number, then 2 and 82,218,065.5 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 | 164,436,131 | |
| -1 | -164,436,131 |
Now, we try dividing 164,436,131 by 3:
164,436,131 ÷ 3 = 54,812,043.6667
If the quotient is a whole number, then 3 and 54,812,043.6667 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 | 164,436,131 | |
| -1 | -164,436,131 |
Let's try dividing by 4:
164,436,131 ÷ 4 = 41,109,032.75
If the quotient is a whole number, then 4 and 41,109,032.75 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 | 164,436,131 | |
| -1 | 164,436,131 |
If you did it right, you will end up with this table:
| 1 | 23 | 113 | 151 | 419 | 2,599 | 3,473 | 9,637 | 17,063 | 47,347 | 63,269 | 392,449 | 1,088,981 | 1,455,187 | 7,149,397 | 164,436,131 |
| -1 | -23 | -113 | -151 | -419 | -2,599 | -3,473 | -9,637 | -17,063 | -47,347 | -63,269 | -392,449 | -1,088,981 | -1,455,187 | -7,149,397 | -164,436,131 |
