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 7,443,065, 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 | 7,443,065 | |
| -1 | -7,443,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,443,065.
Example:
1 x 7,443,065 = 7,443,065
and
-1 x -7,443,065 = 7,443,065
Notice both answers equal 7,443,065
With that explanation out of the way, let's continue. Next, we take the number 7,443,065 and divide it by 2:
7,443,065 ÷ 2 = 3,721,532.5
If the quotient is a whole number, then 2 and 3,721,532.5 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 | 7,443,065 | |
| -1 | -7,443,065 |
Now, we try dividing 7,443,065 by 3:
7,443,065 ÷ 3 = 2,481,021.6667
If the quotient is a whole number, then 3 and 2,481,021.6667 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 | 7,443,065 | |
| -1 | -7,443,065 |
Let's try dividing by 4:
7,443,065 ÷ 4 = 1,860,766.25
If the quotient is a whole number, then 4 and 1,860,766.25 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 | 7,443,065 | |
| -1 | 7,443,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 109 | 545 | 763 | 1,951 | 3,815 | 9,755 | 13,657 | 68,285 | 212,659 | 1,063,295 | 1,488,613 | 7,443,065 |
| -1 | -5 | -7 | -35 | -109 | -545 | -763 | -1,951 | -3,815 | -9,755 | -13,657 | -68,285 | -212,659 | -1,063,295 | -1,488,613 | -7,443,065 |
