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 164,307,155, 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 | 164,307,155 | |
| -1 | -164,307,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,307,155.
Example:
1 x 164,307,155 = 164,307,155
and
-1 x -164,307,155 = 164,307,155
Notice both answers equal 164,307,155
With that explanation out of the way, let's continue. Next, we take the number 164,307,155 and divide it by 2:
164,307,155 ÷ 2 = 82,153,577.5
If the quotient is a whole number, then 2 and 82,153,577.5 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 | 164,307,155 | |
| -1 | -164,307,155 |
Now, we try dividing 164,307,155 by 3:
164,307,155 ÷ 3 = 54,769,051.6667
If the quotient is a whole number, then 3 and 54,769,051.6667 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 | 164,307,155 | |
| -1 | -164,307,155 |
Let's try dividing by 4:
164,307,155 ÷ 4 = 41,076,788.75
If the quotient is a whole number, then 4 and 41,076,788.75 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 | 164,307,155 | |
| -1 | 164,307,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 5,035 | 32,633 | 163,165 | 620,027 | 1,729,549 | 3,100,135 | 8,647,745 | 32,861,431 | 164,307,155 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -5,035 | -32,633 | -163,165 | -620,027 | -1,729,549 | -3,100,135 | -8,647,745 | -32,861,431 | -164,307,155 |
