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 20,035,345, 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 | 20,035,345 | |
| -1 | -20,035,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,035,345.
Example:
1 x 20,035,345 = 20,035,345
and
-1 x -20,035,345 = 20,035,345
Notice both answers equal 20,035,345
With that explanation out of the way, let's continue. Next, we take the number 20,035,345 and divide it by 2:
20,035,345 ÷ 2 = 10,017,672.5
If the quotient is a whole number, then 2 and 10,017,672.5 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 | 20,035,345 | |
| -1 | -20,035,345 |
Now, we try dividing 20,035,345 by 3:
20,035,345 ÷ 3 = 6,678,448.3333
If the quotient is a whole number, then 3 and 6,678,448.3333 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 | 20,035,345 | |
| -1 | -20,035,345 |
Let's try dividing by 4:
20,035,345 ÷ 4 = 5,008,836.25
If the quotient is a whole number, then 4 and 5,008,836.25 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 | 20,035,345 | |
| -1 | 20,035,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 5,437 | 27,185 | 59,807 | 299,035 | 364,279 | 1,821,395 | 4,007,069 | 20,035,345 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -5,437 | -27,185 | -59,807 | -299,035 | -364,279 | -1,821,395 | -4,007,069 | -20,035,345 |
