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 5,230,729, 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 | 5,230,729 | |
| -1 | -5,230,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,230,729.
Example:
1 x 5,230,729 = 5,230,729
and
-1 x -5,230,729 = 5,230,729
Notice both answers equal 5,230,729
With that explanation out of the way, let's continue. Next, we take the number 5,230,729 and divide it by 2:
5,230,729 ÷ 2 = 2,615,364.5
If the quotient is a whole number, then 2 and 2,615,364.5 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 | 5,230,729 | |
| -1 | -5,230,729 |
Now, we try dividing 5,230,729 by 3:
5,230,729 ÷ 3 = 1,743,576.3333
If the quotient is a whole number, then 3 and 1,743,576.3333 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 | 5,230,729 | |
| -1 | -5,230,729 |
Let's try dividing by 4:
5,230,729 ÷ 4 = 1,307,682.25
If the quotient is a whole number, then 4 and 1,307,682.25 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 | 5,230,729 | |
| -1 | 5,230,729 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 53 | 161 | 371 | 613 | 1,219 | 4,291 | 8,533 | 14,099 | 32,489 | 98,693 | 227,423 | 747,247 | 5,230,729 |
| -1 | -7 | -23 | -53 | -161 | -371 | -613 | -1,219 | -4,291 | -8,533 | -14,099 | -32,489 | -98,693 | -227,423 | -747,247 | -5,230,729 |
