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 7,401,205, 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 | 7,401,205 | |
| -1 | -7,401,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,401,205.
Example:
1 x 7,401,205 = 7,401,205
and
-1 x -7,401,205 = 7,401,205
Notice both answers equal 7,401,205
With that explanation out of the way, let's continue. Next, we take the number 7,401,205 and divide it by 2:
7,401,205 ÷ 2 = 3,700,602.5
If the quotient is a whole number, then 2 and 3,700,602.5 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 | 7,401,205 | |
| -1 | -7,401,205 |
Now, we try dividing 7,401,205 by 3:
7,401,205 ÷ 3 = 2,467,068.3333
If the quotient is a whole number, then 3 and 2,467,068.3333 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 | 7,401,205 | |
| -1 | -7,401,205 |
Let's try dividing by 4:
7,401,205 ÷ 4 = 1,850,301.25
If the quotient is a whole number, then 4 and 1,850,301.25 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 | 7,401,205 | |
| -1 | 7,401,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 1,777 | 4,165 | 8,885 | 12,439 | 30,209 | 62,195 | 87,073 | 151,045 | 211,463 | 435,365 | 1,057,315 | 1,480,241 | 7,401,205 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -1,777 | -4,165 | -8,885 | -12,439 | -30,209 | -62,195 | -87,073 | -151,045 | -211,463 | -435,365 | -1,057,315 | -1,480,241 | -7,401,205 |
