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 164,847,235, 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 | 164,847,235 | |
| -1 | -164,847,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,847,235.
Example:
1 x 164,847,235 = 164,847,235
and
-1 x -164,847,235 = 164,847,235
Notice both answers equal 164,847,235
With that explanation out of the way, let's continue. Next, we take the number 164,847,235 and divide it by 2:
164,847,235 ÷ 2 = 82,423,617.5
If the quotient is a whole number, then 2 and 82,423,617.5 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 | 164,847,235 | |
| -1 | -164,847,235 |
Now, we try dividing 164,847,235 by 3:
164,847,235 ÷ 3 = 54,949,078.3333
If the quotient is a whole number, then 3 and 54,949,078.3333 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 | 164,847,235 | |
| -1 | -164,847,235 |
Let's try dividing by 4:
164,847,235 ÷ 4 = 41,211,808.75
If the quotient is a whole number, then 4 and 41,211,808.75 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 | 164,847,235 | |
| -1 | 164,847,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 269 | 1,345 | 1,883 | 9,415 | 17,509 | 87,545 | 122,563 | 612,815 | 4,709,921 | 23,549,605 | 32,969,447 | 164,847,235 |
| -1 | -5 | -7 | -35 | -269 | -1,345 | -1,883 | -9,415 | -17,509 | -87,545 | -122,563 | -612,815 | -4,709,921 | -23,549,605 | -32,969,447 | -164,847,235 |
