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 3,197,437, 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 | 3,197,437 | |
| -1 | -3,197,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,197,437.
Example:
1 x 3,197,437 = 3,197,437
and
-1 x -3,197,437 = 3,197,437
Notice both answers equal 3,197,437
With that explanation out of the way, let's continue. Next, we take the number 3,197,437 and divide it by 2:
3,197,437 ÷ 2 = 1,598,718.5
If the quotient is a whole number, then 2 and 1,598,718.5 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 | 3,197,437 | |
| -1 | -3,197,437 |
Now, we try dividing 3,197,437 by 3:
3,197,437 ÷ 3 = 1,065,812.3333
If the quotient is a whole number, then 3 and 1,065,812.3333 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 | 3,197,437 | |
| -1 | -3,197,437 |
Let's try dividing by 4:
3,197,437 ÷ 4 = 799,359.25
If the quotient is a whole number, then 4 and 799,359.25 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 | 3,197,437 | |
| -1 | 3,197,437 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 53 | 61 | 989 | 1,219 | 1,403 | 2,279 | 2,623 | 3,233 | 52,417 | 60,329 | 74,359 | 139,019 | 3,197,437 |
| -1 | -23 | -43 | -53 | -61 | -989 | -1,219 | -1,403 | -2,279 | -2,623 | -3,233 | -52,417 | -60,329 | -74,359 | -139,019 | -3,197,437 |
