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 3,488,075, 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 | 3,488,075 | |
| -1 | -3,488,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,488,075.
Example:
1 x 3,488,075 = 3,488,075
and
-1 x -3,488,075 = 3,488,075
Notice both answers equal 3,488,075
With that explanation out of the way, let's continue. Next, we take the number 3,488,075 and divide it by 2:
3,488,075 ÷ 2 = 1,744,037.5
If the quotient is a whole number, then 2 and 1,744,037.5 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 | 3,488,075 | |
| -1 | -3,488,075 |
Now, we try dividing 3,488,075 by 3:
3,488,075 ÷ 3 = 1,162,691.6667
If the quotient is a whole number, then 3 and 1,162,691.6667 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 | 3,488,075 | |
| -1 | -3,488,075 |
Let's try dividing by 4:
3,488,075 ÷ 4 = 872,018.75
If the quotient is a whole number, then 4 and 872,018.75 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 | 3,488,075 | |
| -1 | 3,488,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 83 | 205 | 415 | 1,025 | 1,681 | 2,075 | 3,403 | 8,405 | 17,015 | 42,025 | 85,075 | 139,523 | 697,615 | 3,488,075 |
| -1 | -5 | -25 | -41 | -83 | -205 | -415 | -1,025 | -1,681 | -2,075 | -3,403 | -8,405 | -17,015 | -42,025 | -85,075 | -139,523 | -697,615 | -3,488,075 |
