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 2,350,271, 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 | 2,350,271 | |
| -1 | -2,350,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,350,271.
Example:
1 x 2,350,271 = 2,350,271
and
-1 x -2,350,271 = 2,350,271
Notice both answers equal 2,350,271
With that explanation out of the way, let's continue. Next, we take the number 2,350,271 and divide it by 2:
2,350,271 ÷ 2 = 1,175,135.5
If the quotient is a whole number, then 2 and 1,175,135.5 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 | 2,350,271 | |
| -1 | -2,350,271 |
Now, we try dividing 2,350,271 by 3:
2,350,271 ÷ 3 = 783,423.6667
If the quotient is a whole number, then 3 and 783,423.6667 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 | 2,350,271 | |
| -1 | -2,350,271 |
Let's try dividing by 4:
2,350,271 ÷ 4 = 587,567.75
If the quotient is a whole number, then 4 and 587,567.75 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 | 2,350,271 | |
| -1 | 2,350,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 131 | 233 | 917 | 1,441 | 1,631 | 2,563 | 10,087 | 17,941 | 30,523 | 213,661 | 335,753 | 2,350,271 |
| -1 | -7 | -11 | -77 | -131 | -233 | -917 | -1,441 | -1,631 | -2,563 | -10,087 | -17,941 | -30,523 | -213,661 | -335,753 | -2,350,271 |
