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 20,000,351, 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 | 20,000,351 | |
| -1 | -20,000,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,000,351.
Example:
1 x 20,000,351 = 20,000,351
and
-1 x -20,000,351 = 20,000,351
Notice both answers equal 20,000,351
With that explanation out of the way, let's continue. Next, we take the number 20,000,351 and divide it by 2:
20,000,351 ÷ 2 = 10,000,175.5
If the quotient is a whole number, then 2 and 10,000,175.5 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 | 20,000,351 | |
| -1 | -20,000,351 |
Now, we try dividing 20,000,351 by 3:
20,000,351 ÷ 3 = 6,666,783.6667
If the quotient is a whole number, then 3 and 6,666,783.6667 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 | 20,000,351 | |
| -1 | -20,000,351 |
Let's try dividing by 4:
20,000,351 ÷ 4 = 5,000,087.75
If the quotient is a whole number, then 4 and 5,000,087.75 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 | 20,000,351 | |
| -1 | 20,000,351 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 79 | 413 | 553 | 613 | 4,291 | 4,661 | 32,627 | 36,167 | 48,427 | 253,169 | 338,989 | 2,857,193 | 20,000,351 |
| -1 | -7 | -59 | -79 | -413 | -553 | -613 | -4,291 | -4,661 | -32,627 | -36,167 | -48,427 | -253,169 | -338,989 | -2,857,193 | -20,000,351 |
