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 7,341,257, 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 | 7,341,257 | |
| -1 | -7,341,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,341,257.
Example:
1 x 7,341,257 = 7,341,257
and
-1 x -7,341,257 = 7,341,257
Notice both answers equal 7,341,257
With that explanation out of the way, let's continue. Next, we take the number 7,341,257 and divide it by 2:
7,341,257 ÷ 2 = 3,670,628.5
If the quotient is a whole number, then 2 and 3,670,628.5 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 | 7,341,257 | |
| -1 | -7,341,257 |
Now, we try dividing 7,341,257 by 3:
7,341,257 ÷ 3 = 2,447,085.6667
If the quotient is a whole number, then 3 and 2,447,085.6667 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 | 7,341,257 | |
| -1 | -7,341,257 |
Let's try dividing by 4:
7,341,257 ÷ 4 = 1,835,314.25
If the quotient is a whole number, then 4 and 1,835,314.25 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 | 7,341,257 | |
| -1 | 7,341,257 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 737 | 1,423 | 5,159 | 9,961 | 15,653 | 95,341 | 109,571 | 667,387 | 1,048,751 | 7,341,257 |
| -1 | -7 | -11 | -67 | -77 | -469 | -737 | -1,423 | -5,159 | -9,961 | -15,653 | -95,341 | -109,571 | -667,387 | -1,048,751 | -7,341,257 |
