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 167,104,405, 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 | 167,104,405 | |
| -1 | -167,104,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,104,405.
Example:
1 x 167,104,405 = 167,104,405
and
-1 x -167,104,405 = 167,104,405
Notice both answers equal 167,104,405
With that explanation out of the way, let's continue. Next, we take the number 167,104,405 and divide it by 2:
167,104,405 ÷ 2 = 83,552,202.5
If the quotient is a whole number, then 2 and 83,552,202.5 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 | 167,104,405 | |
| -1 | -167,104,405 |
Now, we try dividing 167,104,405 by 3:
167,104,405 ÷ 3 = 55,701,468.3333
If the quotient is a whole number, then 3 and 55,701,468.3333 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 | 167,104,405 | |
| -1 | -167,104,405 |
Let's try dividing by 4:
167,104,405 ÷ 4 = 41,776,101.25
If the quotient is a whole number, then 4 and 41,776,101.25 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 | 167,104,405 | |
| -1 | 167,104,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 277 | 1,385 | 3,601 | 9,281 | 18,005 | 46,405 | 120,653 | 603,265 | 2,570,837 | 12,854,185 | 33,420,881 | 167,104,405 |
| -1 | -5 | -13 | -65 | -277 | -1,385 | -3,601 | -9,281 | -18,005 | -46,405 | -120,653 | -603,265 | -2,570,837 | -12,854,185 | -33,420,881 | -167,104,405 |
