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 7,744,885, 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 | 7,744,885 | |
| -1 | -7,744,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,744,885.
Example:
1 x 7,744,885 = 7,744,885
and
-1 x -7,744,885 = 7,744,885
Notice both answers equal 7,744,885
With that explanation out of the way, let's continue. Next, we take the number 7,744,885 and divide it by 2:
7,744,885 ÷ 2 = 3,872,442.5
If the quotient is a whole number, then 2 and 3,872,442.5 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 | 7,744,885 | |
| -1 | -7,744,885 |
Now, we try dividing 7,744,885 by 3:
7,744,885 ÷ 3 = 2,581,628.3333
If the quotient is a whole number, then 3 and 2,581,628.3333 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 | 7,744,885 | |
| -1 | -7,744,885 |
Let's try dividing by 4:
7,744,885 ÷ 4 = 1,936,221.25
If the quotient is a whole number, then 4 and 1,936,221.25 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 | 7,744,885 | |
| -1 | 7,744,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 1,723 | 4,495 | 8,615 | 49,967 | 53,413 | 249,835 | 267,065 | 1,548,977 | 7,744,885 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -1,723 | -4,495 | -8,615 | -49,967 | -53,413 | -249,835 | -267,065 | -1,548,977 | -7,744,885 |
