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 3,368,147, 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 | 3,368,147 | |
| -1 | -3,368,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,368,147.
Example:
1 x 3,368,147 = 3,368,147
and
-1 x -3,368,147 = 3,368,147
Notice both answers equal 3,368,147
With that explanation out of the way, let's continue. Next, we take the number 3,368,147 and divide it by 2:
3,368,147 ÷ 2 = 1,684,073.5
If the quotient is a whole number, then 2 and 1,684,073.5 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 | 3,368,147 | |
| -1 | -3,368,147 |
Now, we try dividing 3,368,147 by 3:
3,368,147 ÷ 3 = 1,122,715.6667
If the quotient is a whole number, then 3 and 1,122,715.6667 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 | 3,368,147 | |
| -1 | -3,368,147 |
Let's try dividing by 4:
3,368,147 ÷ 4 = 842,036.75
If the quotient is a whole number, then 4 and 842,036.75 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 | 3,368,147 | |
| -1 | 3,368,147 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 43 | 73 | 1,073 | 1,247 | 1,591 | 2,117 | 2,701 | 3,139 | 46,139 | 78,329 | 91,031 | 116,143 | 3,368,147 |
| -1 | -29 | -37 | -43 | -73 | -1,073 | -1,247 | -1,591 | -2,117 | -2,701 | -3,139 | -46,139 | -78,329 | -91,031 | -116,143 | -3,368,147 |
