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 3,520,513, 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 | 3,520,513 | |
| -1 | -3,520,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,520,513.
Example:
1 x 3,520,513 = 3,520,513
and
-1 x -3,520,513 = 3,520,513
Notice both answers equal 3,520,513
With that explanation out of the way, let's continue. Next, we take the number 3,520,513 and divide it by 2:
3,520,513 ÷ 2 = 1,760,256.5
If the quotient is a whole number, then 2 and 1,760,256.5 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 | 3,520,513 | |
| -1 | -3,520,513 |
Now, we try dividing 3,520,513 by 3:
3,520,513 ÷ 3 = 1,173,504.3333
If the quotient is a whole number, then 3 and 1,173,504.3333 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 | 3,520,513 | |
| -1 | -3,520,513 |
Let's try dividing by 4:
3,520,513 ÷ 4 = 880,128.25
If the quotient is a whole number, then 4 and 880,128.25 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 | 3,520,513 | |
| -1 | 3,520,513 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 193 | 493 | 629 | 1,073 | 3,281 | 5,597 | 7,141 | 18,241 | 95,149 | 121,397 | 207,089 | 3,520,513 |
| -1 | -17 | -29 | -37 | -193 | -493 | -629 | -1,073 | -3,281 | -5,597 | -7,141 | -18,241 | -95,149 | -121,397 | -207,089 | -3,520,513 |
