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 15,241,211, 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 | 15,241,211 | |
| -1 | -15,241,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,241,211.
Example:
1 x 15,241,211 = 15,241,211
and
-1 x -15,241,211 = 15,241,211
Notice both answers equal 15,241,211
With that explanation out of the way, let's continue. Next, we take the number 15,241,211 and divide it by 2:
15,241,211 ÷ 2 = 7,620,605.5
If the quotient is a whole number, then 2 and 7,620,605.5 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 | 15,241,211 | |
| -1 | -15,241,211 |
Now, we try dividing 15,241,211 by 3:
15,241,211 ÷ 3 = 5,080,403.6667
If the quotient is a whole number, then 3 and 5,080,403.6667 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 | 15,241,211 | |
| -1 | -15,241,211 |
Let's try dividing by 4:
15,241,211 ÷ 4 = 3,810,302.75
If the quotient is a whole number, then 4 and 3,810,302.75 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 | 15,241,211 | |
| -1 | 15,241,211 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 139 | 199 | 551 | 2,641 | 3,781 | 4,031 | 5,771 | 27,661 | 76,589 | 109,649 | 525,559 | 802,169 | 15,241,211 |
| -1 | -19 | -29 | -139 | -199 | -551 | -2,641 | -3,781 | -4,031 | -5,771 | -27,661 | -76,589 | -109,649 | -525,559 | -802,169 | -15,241,211 |
