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 7,534,205, 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 | 7,534,205 | |
| -1 | -7,534,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,534,205.
Example:
1 x 7,534,205 = 7,534,205
and
-1 x -7,534,205 = 7,534,205
Notice both answers equal 7,534,205
With that explanation out of the way, let's continue. Next, we take the number 7,534,205 and divide it by 2:
7,534,205 ÷ 2 = 3,767,102.5
If the quotient is a whole number, then 2 and 3,767,102.5 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 | 7,534,205 | |
| -1 | -7,534,205 |
Now, we try dividing 7,534,205 by 3:
7,534,205 ÷ 3 = 2,511,401.6667
If the quotient is a whole number, then 3 and 2,511,401.6667 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 | 7,534,205 | |
| -1 | -7,534,205 |
Let's try dividing by 4:
7,534,205 ÷ 4 = 1,883,551.25
If the quotient is a whole number, then 4 and 1,883,551.25 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 | 7,534,205 | |
| -1 | 7,534,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 167 | 835 | 1,169 | 1,289 | 5,845 | 6,445 | 9,023 | 45,115 | 215,263 | 1,076,315 | 1,506,841 | 7,534,205 |
| -1 | -5 | -7 | -35 | -167 | -835 | -1,169 | -1,289 | -5,845 | -6,445 | -9,023 | -45,115 | -215,263 | -1,076,315 | -1,506,841 | -7,534,205 |
