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 3,336,671, 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 | 3,336,671 | |
| -1 | -3,336,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,336,671.
Example:
1 x 3,336,671 = 3,336,671
and
-1 x -3,336,671 = 3,336,671
Notice both answers equal 3,336,671
With that explanation out of the way, let's continue. Next, we take the number 3,336,671 and divide it by 2:
3,336,671 ÷ 2 = 1,668,335.5
If the quotient is a whole number, then 2 and 1,668,335.5 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 | 3,336,671 | |
| -1 | -3,336,671 |
Now, we try dividing 3,336,671 by 3:
3,336,671 ÷ 3 = 1,112,223.6667
If the quotient is a whole number, then 3 and 1,112,223.6667 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 | 3,336,671 | |
| -1 | -3,336,671 |
Let's try dividing by 4:
3,336,671 ÷ 4 = 834,167.75
If the quotient is a whole number, then 4 and 834,167.75 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 | 3,336,671 | |
| -1 | 3,336,671 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 47 | 127 | 559 | 611 | 1,651 | 2,021 | 5,461 | 5,969 | 26,273 | 70,993 | 77,597 | 256,667 | 3,336,671 |
| -1 | -13 | -43 | -47 | -127 | -559 | -611 | -1,651 | -2,021 | -5,461 | -5,969 | -26,273 | -70,993 | -77,597 | -256,667 | -3,336,671 |
