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 7,783,825, 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 | 7,783,825 | |
| -1 | -7,783,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,783,825.
Example:
1 x 7,783,825 = 7,783,825
and
-1 x -7,783,825 = 7,783,825
Notice both answers equal 7,783,825
With that explanation out of the way, let's continue. Next, we take the number 7,783,825 and divide it by 2:
7,783,825 ÷ 2 = 3,891,912.5
If the quotient is a whole number, then 2 and 3,891,912.5 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 | 7,783,825 | |
| -1 | -7,783,825 |
Now, we try dividing 7,783,825 by 3:
7,783,825 ÷ 3 = 2,594,608.3333
If the quotient is a whole number, then 3 and 2,594,608.3333 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 | 7,783,825 | |
| -1 | -7,783,825 |
Let's try dividing by 4:
7,783,825 ÷ 4 = 1,945,956.25
If the quotient is a whole number, then 4 and 1,945,956.25 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 | 7,783,825 | |
| -1 | 7,783,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 2,341 | 3,325 | 11,705 | 16,387 | 44,479 | 58,525 | 81,935 | 222,395 | 311,353 | 409,675 | 1,111,975 | 1,556,765 | 7,783,825 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -2,341 | -3,325 | -11,705 | -16,387 | -44,479 | -58,525 | -81,935 | -222,395 | -311,353 | -409,675 | -1,111,975 | -1,556,765 | -7,783,825 |
