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 4,868,647, 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 | 4,868,647 | |
| -1 | -4,868,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,868,647.
Example:
1 x 4,868,647 = 4,868,647
and
-1 x -4,868,647 = 4,868,647
Notice both answers equal 4,868,647
With that explanation out of the way, let's continue. Next, we take the number 4,868,647 and divide it by 2:
4,868,647 ÷ 2 = 2,434,323.5
If the quotient is a whole number, then 2 and 2,434,323.5 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 | 4,868,647 | |
| -1 | -4,868,647 |
Now, we try dividing 4,868,647 by 3:
4,868,647 ÷ 3 = 1,622,882.3333
If the quotient is a whole number, then 3 and 1,622,882.3333 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 | 4,868,647 | |
| -1 | -4,868,647 |
Let's try dividing by 4:
4,868,647 ÷ 4 = 1,217,161.75
If the quotient is a whole number, then 4 and 1,217,161.75 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 | 4,868,647 | |
| -1 | 4,868,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 163 | 251 | 1,141 | 1,757 | 2,771 | 4,267 | 19,397 | 29,869 | 40,913 | 286,391 | 695,521 | 4,868,647 |
| -1 | -7 | -17 | -119 | -163 | -251 | -1,141 | -1,757 | -2,771 | -4,267 | -19,397 | -29,869 | -40,913 | -286,391 | -695,521 | -4,868,647 |
