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 15,304,121, 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 | 15,304,121 | |
| -1 | -15,304,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,304,121.
Example:
1 x 15,304,121 = 15,304,121
and
-1 x -15,304,121 = 15,304,121
Notice both answers equal 15,304,121
With that explanation out of the way, let's continue. Next, we take the number 15,304,121 and divide it by 2:
15,304,121 ÷ 2 = 7,652,060.5
If the quotient is a whole number, then 2 and 7,652,060.5 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 | 15,304,121 | |
| -1 | -15,304,121 |
Now, we try dividing 15,304,121 by 3:
15,304,121 ÷ 3 = 5,101,373.6667
If the quotient is a whole number, then 3 and 5,101,373.6667 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 | 15,304,121 | |
| -1 | -15,304,121 |
Let's try dividing by 4:
15,304,121 ÷ 4 = 3,826,030.25
If the quotient is a whole number, then 4 and 3,826,030.25 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 | 15,304,121 | |
| -1 | 15,304,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 53 | 71 | 83 | 371 | 497 | 581 | 2,597 | 3,479 | 3,763 | 4,067 | 4,399 | 5,893 | 26,341 | 30,793 | 41,251 | 184,387 | 215,551 | 288,757 | 312,329 | 2,186,303 | 15,304,121 |
| -1 | -7 | -49 | -53 | -71 | -83 | -371 | -497 | -581 | -2,597 | -3,479 | -3,763 | -4,067 | -4,399 | -5,893 | -26,341 | -30,793 | -41,251 | -184,387 | -215,551 | -288,757 | -312,329 | -2,186,303 | -15,304,121 |
