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 20,130,035, 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 | 20,130,035 | |
| -1 | -20,130,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,130,035.
Example:
1 x 20,130,035 = 20,130,035
and
-1 x -20,130,035 = 20,130,035
Notice both answers equal 20,130,035
With that explanation out of the way, let's continue. Next, we take the number 20,130,035 and divide it by 2:
20,130,035 ÷ 2 = 10,065,017.5
If the quotient is a whole number, then 2 and 10,065,017.5 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 | 20,130,035 | |
| -1 | -20,130,035 |
Now, we try dividing 20,130,035 by 3:
20,130,035 ÷ 3 = 6,710,011.6667
If the quotient is a whole number, then 3 and 6,710,011.6667 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 | 20,130,035 | |
| -1 | -20,130,035 |
Let's try dividing by 4:
20,130,035 ÷ 4 = 5,032,508.75
If the quotient is a whole number, then 4 and 5,032,508.75 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 | 20,130,035 | |
| -1 | 20,130,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 233 | 467 | 1,165 | 2,335 | 8,621 | 17,279 | 43,105 | 86,395 | 108,811 | 544,055 | 4,026,007 | 20,130,035 |
| -1 | -5 | -37 | -185 | -233 | -467 | -1,165 | -2,335 | -8,621 | -17,279 | -43,105 | -86,395 | -108,811 | -544,055 | -4,026,007 | -20,130,035 |
