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 15,051,035, 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 | 15,051,035 | |
| -1 | -15,051,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,051,035.
Example:
1 x 15,051,035 = 15,051,035
and
-1 x -15,051,035 = 15,051,035
Notice both answers equal 15,051,035
With that explanation out of the way, let's continue. Next, we take the number 15,051,035 and divide it by 2:
15,051,035 ÷ 2 = 7,525,517.5
If the quotient is a whole number, then 2 and 7,525,517.5 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 | 15,051,035 | |
| -1 | -15,051,035 |
Now, we try dividing 15,051,035 by 3:
15,051,035 ÷ 3 = 5,017,011.6667
If the quotient is a whole number, then 3 and 5,017,011.6667 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 | 15,051,035 | |
| -1 | -15,051,035 |
Let's try dividing by 4:
15,051,035 ÷ 4 = 3,762,758.75
If the quotient is a whole number, then 4 and 3,762,758.75 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 | 15,051,035 | |
| -1 | 15,051,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 565 | 1,567 | 1,921 | 7,835 | 9,605 | 26,639 | 133,195 | 177,071 | 885,355 | 3,010,207 | 15,051,035 |
| -1 | -5 | -17 | -85 | -113 | -565 | -1,567 | -1,921 | -7,835 | -9,605 | -26,639 | -133,195 | -177,071 | -885,355 | -3,010,207 | -15,051,035 |
