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 4,819,619, 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 | 4,819,619 | |
| -1 | -4,819,619 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,819,619.
Example:
1 x 4,819,619 = 4,819,619
and
-1 x -4,819,619 = 4,819,619
Notice both answers equal 4,819,619
With that explanation out of the way, let's continue. Next, we take the number 4,819,619 and divide it by 2:
4,819,619 ÷ 2 = 2,409,809.5
If the quotient is a whole number, then 2 and 2,409,809.5 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 | 4,819,619 | |
| -1 | -4,819,619 |
Now, we try dividing 4,819,619 by 3:
4,819,619 ÷ 3 = 1,606,539.6667
If the quotient is a whole number, then 3 and 1,606,539.6667 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 | 4,819,619 | |
| -1 | -4,819,619 |
Let's try dividing by 4:
4,819,619 ÷ 4 = 1,204,904.75
If the quotient is a whole number, then 4 and 1,204,904.75 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 | 4,819,619 | |
| -1 | 4,819,619 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 101 | 119 | 401 | 707 | 1,717 | 2,807 | 6,817 | 12,019 | 40,501 | 47,719 | 283,507 | 688,517 | 4,819,619 |
| -1 | -7 | -17 | -101 | -119 | -401 | -707 | -1,717 | -2,807 | -6,817 | -12,019 | -40,501 | -47,719 | -283,507 | -688,517 | -4,819,619 |
