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 4,309,279, 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 | 4,309,279 | |
| -1 | -4,309,279 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,309,279.
Example:
1 x 4,309,279 = 4,309,279
and
-1 x -4,309,279 = 4,309,279
Notice both answers equal 4,309,279
With that explanation out of the way, let's continue. Next, we take the number 4,309,279 and divide it by 2:
4,309,279 ÷ 2 = 2,154,639.5
If the quotient is a whole number, then 2 and 2,154,639.5 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 | 4,309,279 | |
| -1 | -4,309,279 |
Now, we try dividing 4,309,279 by 3:
4,309,279 ÷ 3 = 1,436,426.3333
If the quotient is a whole number, then 3 and 1,436,426.3333 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 | 4,309,279 | |
| -1 | -4,309,279 |
Let's try dividing by 4:
4,309,279 ÷ 4 = 1,077,319.75
If the quotient is a whole number, then 4 and 1,077,319.75 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 | 4,309,279 | |
| -1 | 4,309,279 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 37 | 221 | 289 | 403 | 481 | 527 | 629 | 1,147 | 3,757 | 6,851 | 8,177 | 8,959 | 10,693 | 14,911 | 19,499 | 116,467 | 139,009 | 253,487 | 331,483 | 4,309,279 |
