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 3,597,217, 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 | 3,597,217 | |
| -1 | -3,597,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,597,217.
Example:
1 x 3,597,217 = 3,597,217
and
-1 x -3,597,217 = 3,597,217
Notice both answers equal 3,597,217
With that explanation out of the way, let's continue. Next, we take the number 3,597,217 and divide it by 2:
3,597,217 ÷ 2 = 1,798,608.5
If the quotient is a whole number, then 2 and 1,798,608.5 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 | 3,597,217 | |
| -1 | -3,597,217 |
Now, we try dividing 3,597,217 by 3:
3,597,217 ÷ 3 = 1,199,072.3333
If the quotient is a whole number, then 3 and 1,199,072.3333 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 | 3,597,217 | |
| -1 | -3,597,217 |
Let's try dividing by 4:
3,597,217 ÷ 4 = 899,304.25
If the quotient is a whole number, then 4 and 899,304.25 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 | 3,597,217 | |
| -1 | 3,597,217 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 397 | 533 | 697 | 5,161 | 6,749 | 9,061 | 16,277 | 87,737 | 211,601 | 276,709 | 3,597,217 |
| -1 | -13 | -17 | -41 | -221 | -397 | -533 | -697 | -5,161 | -6,749 | -9,061 | -16,277 | -87,737 | -211,601 | -276,709 | -3,597,217 |
