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 3,418,547, 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 | 3,418,547 | |
| -1 | -3,418,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,418,547.
Example:
1 x 3,418,547 = 3,418,547
and
-1 x -3,418,547 = 3,418,547
Notice both answers equal 3,418,547
With that explanation out of the way, let's continue. Next, we take the number 3,418,547 and divide it by 2:
3,418,547 ÷ 2 = 1,709,273.5
If the quotient is a whole number, then 2 and 1,709,273.5 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 | 3,418,547 | |
| -1 | -3,418,547 |
Now, we try dividing 3,418,547 by 3:
3,418,547 ÷ 3 = 1,139,515.6667
If the quotient is a whole number, then 3 and 1,139,515.6667 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 | 3,418,547 | |
| -1 | -3,418,547 |
Let's try dividing by 4:
3,418,547 ÷ 4 = 854,636.75
If the quotient is a whole number, then 4 and 854,636.75 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 | 3,418,547 | |
| -1 | 3,418,547 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 101 | 181 | 187 | 1,111 | 1,717 | 1,991 | 3,077 | 18,281 | 18,887 | 33,847 | 201,091 | 310,777 | 3,418,547 |
| -1 | -11 | -17 | -101 | -181 | -187 | -1,111 | -1,717 | -1,991 | -3,077 | -18,281 | -18,887 | -33,847 | -201,091 | -310,777 | -3,418,547 |
