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 5,166,421, 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 | 5,166,421 | |
| -1 | -5,166,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,166,421.
Example:
1 x 5,166,421 = 5,166,421
and
-1 x -5,166,421 = 5,166,421
Notice both answers equal 5,166,421
With that explanation out of the way, let's continue. Next, we take the number 5,166,421 and divide it by 2:
5,166,421 ÷ 2 = 2,583,210.5
If the quotient is a whole number, then 2 and 2,583,210.5 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 | 5,166,421 | |
| -1 | -5,166,421 |
Now, we try dividing 5,166,421 by 3:
5,166,421 ÷ 3 = 1,722,140.3333
If the quotient is a whole number, then 3 and 1,722,140.3333 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 | 5,166,421 | |
| -1 | -5,166,421 |
Let's try dividing by 4:
5,166,421 ÷ 4 = 1,291,605.25
If the quotient is a whole number, then 4 and 1,291,605.25 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 | 5,166,421 | |
| -1 | 5,166,421 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 37 | 299 | 467 | 481 | 851 | 6,071 | 10,741 | 11,063 | 17,279 | 139,633 | 224,627 | 397,417 | 5,166,421 |
| -1 | -13 | -23 | -37 | -299 | -467 | -481 | -851 | -6,071 | -10,741 | -11,063 | -17,279 | -139,633 | -224,627 | -397,417 | -5,166,421 |
