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 3,413,125, 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 | 3,413,125 | |
| -1 | -3,413,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,413,125.
Example:
1 x 3,413,125 = 3,413,125
and
-1 x -3,413,125 = 3,413,125
Notice both answers equal 3,413,125
With that explanation out of the way, let's continue. Next, we take the number 3,413,125 and divide it by 2:
3,413,125 ÷ 2 = 1,706,562.5
If the quotient is a whole number, then 2 and 1,706,562.5 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 | 3,413,125 | |
| -1 | -3,413,125 |
Now, we try dividing 3,413,125 by 3:
3,413,125 ÷ 3 = 1,137,708.3333
If the quotient is a whole number, then 3 and 1,137,708.3333 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 | 3,413,125 | |
| -1 | -3,413,125 |
Let's try dividing by 4:
3,413,125 ÷ 4 = 853,281.25
If the quotient is a whole number, then 4 and 853,281.25 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 | 3,413,125 | |
| -1 | 3,413,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 127 | 215 | 625 | 635 | 1,075 | 3,175 | 5,375 | 5,461 | 15,875 | 26,875 | 27,305 | 79,375 | 136,525 | 682,625 | 3,413,125 |
| -1 | -5 | -25 | -43 | -125 | -127 | -215 | -625 | -635 | -1,075 | -3,175 | -5,375 | -5,461 | -15,875 | -26,875 | -27,305 | -79,375 | -136,525 | -682,625 | -3,413,125 |
