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 15,355,039, 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 | 15,355,039 | |
| -1 | -15,355,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,355,039.
Example:
1 x 15,355,039 = 15,355,039
and
-1 x -15,355,039 = 15,355,039
Notice both answers equal 15,355,039
With that explanation out of the way, let's continue. Next, we take the number 15,355,039 and divide it by 2:
15,355,039 ÷ 2 = 7,677,519.5
If the quotient is a whole number, then 2 and 7,677,519.5 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 | 15,355,039 | |
| -1 | -15,355,039 |
Now, we try dividing 15,355,039 by 3:
15,355,039 ÷ 3 = 5,118,346.3333
If the quotient is a whole number, then 3 and 5,118,346.3333 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 | 15,355,039 | |
| -1 | -15,355,039 |
Let's try dividing by 4:
15,355,039 ÷ 4 = 3,838,759.75
If the quotient is a whole number, then 4 and 3,838,759.75 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 | 15,355,039 | |
| -1 | 15,355,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 151 | 199 | 511 | 1,057 | 1,393 | 11,023 | 14,527 | 30,049 | 77,161 | 101,689 | 210,343 | 2,193,577 | 15,355,039 |
| -1 | -7 | -73 | -151 | -199 | -511 | -1,057 | -1,393 | -11,023 | -14,527 | -30,049 | -77,161 | -101,689 | -210,343 | -2,193,577 | -15,355,039 |
