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 3,847,519, 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 | 3,847,519 | |
| -1 | -3,847,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,847,519.
Example:
1 x 3,847,519 = 3,847,519
and
-1 x -3,847,519 = 3,847,519
Notice both answers equal 3,847,519
With that explanation out of the way, let's continue. Next, we take the number 3,847,519 and divide it by 2:
3,847,519 ÷ 2 = 1,923,759.5
If the quotient is a whole number, then 2 and 1,923,759.5 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 | 3,847,519 | |
| -1 | -3,847,519 |
Now, we try dividing 3,847,519 by 3:
3,847,519 ÷ 3 = 1,282,506.3333
If the quotient is a whole number, then 3 and 1,282,506.3333 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 | 3,847,519 | |
| -1 | -3,847,519 |
Let's try dividing by 4:
3,847,519 ÷ 4 = 961,879.75
If the quotient is a whole number, then 4 and 961,879.75 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 | 3,847,519 | |
| -1 | 3,847,519 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 421 | 481 | 703 | 5,473 | 7,999 | 9,139 | 15,577 | 103,987 | 202,501 | 295,963 | 3,847,519 |
| -1 | -13 | -19 | -37 | -247 | -421 | -481 | -703 | -5,473 | -7,999 | -9,139 | -15,577 | -103,987 | -202,501 | -295,963 | -3,847,519 |
