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 164,231,345, 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 | 164,231,345 | |
| -1 | -164,231,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,231,345.
Example:
1 x 164,231,345 = 164,231,345
and
-1 x -164,231,345 = 164,231,345
Notice both answers equal 164,231,345
With that explanation out of the way, let's continue. Next, we take the number 164,231,345 and divide it by 2:
164,231,345 ÷ 2 = 82,115,672.5
If the quotient is a whole number, then 2 and 82,115,672.5 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 | 164,231,345 | |
| -1 | -164,231,345 |
Now, we try dividing 164,231,345 by 3:
164,231,345 ÷ 3 = 54,743,781.6667
If the quotient is a whole number, then 3 and 54,743,781.6667 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 | 164,231,345 | |
| -1 | -164,231,345 |
Let's try dividing by 4:
164,231,345 ÷ 4 = 41,057,836.25
If the quotient is a whole number, then 4 and 41,057,836.25 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 | 164,231,345 | |
| -1 | 164,231,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 46,723 | 233,615 | 887,737 | 1,728,751 | 4,438,685 | 8,643,755 | 32,846,269 | 164,231,345 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -46,723 | -233,615 | -887,737 | -1,728,751 | -4,438,685 | -8,643,755 | -32,846,269 | -164,231,345 |
