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 3,513,271, 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 | 3,513,271 | |
| -1 | -3,513,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,513,271.
Example:
1 x 3,513,271 = 3,513,271
and
-1 x -3,513,271 = 3,513,271
Notice both answers equal 3,513,271
With that explanation out of the way, let's continue. Next, we take the number 3,513,271 and divide it by 2:
3,513,271 ÷ 2 = 1,756,635.5
If the quotient is a whole number, then 2 and 1,756,635.5 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 | 3,513,271 | |
| -1 | -3,513,271 |
Now, we try dividing 3,513,271 by 3:
3,513,271 ÷ 3 = 1,171,090.3333
If the quotient is a whole number, then 3 and 1,171,090.3333 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 | 3,513,271 | |
| -1 | -3,513,271 |
Let's try dividing by 4:
3,513,271 ÷ 4 = 878,317.75
If the quotient is a whole number, then 4 and 878,317.75 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 | 3,513,271 | |
| -1 | 3,513,271 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 73 | 149 | 323 | 1,241 | 1,387 | 2,533 | 2,831 | 10,877 | 23,579 | 48,127 | 184,909 | 206,663 | 3,513,271 |
| -1 | -17 | -19 | -73 | -149 | -323 | -1,241 | -1,387 | -2,533 | -2,831 | -10,877 | -23,579 | -48,127 | -184,909 | -206,663 | -3,513,271 |
