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 15,058,295, 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 | 15,058,295 | |
| -1 | -15,058,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,058,295.
Example:
1 x 15,058,295 = 15,058,295
and
-1 x -15,058,295 = 15,058,295
Notice both answers equal 15,058,295
With that explanation out of the way, let's continue. Next, we take the number 15,058,295 and divide it by 2:
15,058,295 ÷ 2 = 7,529,147.5
If the quotient is a whole number, then 2 and 7,529,147.5 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 | 15,058,295 | |
| -1 | -15,058,295 |
Now, we try dividing 15,058,295 by 3:
15,058,295 ÷ 3 = 5,019,431.6667
If the quotient is a whole number, then 3 and 5,019,431.6667 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 | 15,058,295 | |
| -1 | -15,058,295 |
Let's try dividing by 4:
15,058,295 ÷ 4 = 3,764,573.75
If the quotient is a whole number, then 4 and 3,764,573.75 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 | 15,058,295 | |
| -1 | 15,058,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 905 | 1,267 | 2,377 | 6,335 | 11,885 | 16,639 | 83,195 | 430,237 | 2,151,185 | 3,011,659 | 15,058,295 |
| -1 | -5 | -7 | -35 | -181 | -905 | -1,267 | -2,377 | -6,335 | -11,885 | -16,639 | -83,195 | -430,237 | -2,151,185 | -3,011,659 | -15,058,295 |
