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 7,384,405, 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 | 7,384,405 | |
| -1 | -7,384,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,384,405.
Example:
1 x 7,384,405 = 7,384,405
and
-1 x -7,384,405 = 7,384,405
Notice both answers equal 7,384,405
With that explanation out of the way, let's continue. Next, we take the number 7,384,405 and divide it by 2:
7,384,405 ÷ 2 = 3,692,202.5
If the quotient is a whole number, then 2 and 3,692,202.5 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 | 7,384,405 | |
| -1 | -7,384,405 |
Now, we try dividing 7,384,405 by 3:
7,384,405 ÷ 3 = 2,461,468.3333
If the quotient is a whole number, then 3 and 2,461,468.3333 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 | 7,384,405 | |
| -1 | -7,384,405 |
Let's try dividing by 4:
7,384,405 ÷ 4 = 1,846,101.25
If the quotient is a whole number, then 4 and 1,846,101.25 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 | 7,384,405 | |
| -1 | 7,384,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 67 | 235 | 329 | 335 | 469 | 1,645 | 2,345 | 3,149 | 4,489 | 15,745 | 22,043 | 22,445 | 31,423 | 110,215 | 157,115 | 210,983 | 1,054,915 | 1,476,881 | 7,384,405 |
| -1 | -5 | -7 | -35 | -47 | -67 | -235 | -329 | -335 | -469 | -1,645 | -2,345 | -3,149 | -4,489 | -15,745 | -22,043 | -22,445 | -31,423 | -110,215 | -157,115 | -210,983 | -1,054,915 | -1,476,881 | -7,384,405 |
