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 20,067,505, 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 | 20,067,505 | |
| -1 | -20,067,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,067,505.
Example:
1 x 20,067,505 = 20,067,505
and
-1 x -20,067,505 = 20,067,505
Notice both answers equal 20,067,505
With that explanation out of the way, let's continue. Next, we take the number 20,067,505 and divide it by 2:
20,067,505 ÷ 2 = 10,033,752.5
If the quotient is a whole number, then 2 and 10,033,752.5 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 | 20,067,505 | |
| -1 | -20,067,505 |
Now, we try dividing 20,067,505 by 3:
20,067,505 ÷ 3 = 6,689,168.3333
If the quotient is a whole number, then 3 and 6,689,168.3333 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 | 20,067,505 | |
| -1 | -20,067,505 |
Let's try dividing by 4:
20,067,505 ÷ 4 = 5,016,876.25
If the quotient is a whole number, then 4 and 5,016,876.25 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 | 20,067,505 | |
| -1 | 20,067,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 1,619 | 2,479 | 8,095 | 12,395 | 59,903 | 108,473 | 299,515 | 542,365 | 4,013,501 | 20,067,505 |
| -1 | -5 | -37 | -67 | -185 | -335 | -1,619 | -2,479 | -8,095 | -12,395 | -59,903 | -108,473 | -299,515 | -542,365 | -4,013,501 | -20,067,505 |
