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 15,233,275, 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 | 15,233,275 | |
| -1 | -15,233,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,233,275.
Example:
1 x 15,233,275 = 15,233,275
and
-1 x -15,233,275 = 15,233,275
Notice both answers equal 15,233,275
With that explanation out of the way, let's continue. Next, we take the number 15,233,275 and divide it by 2:
15,233,275 ÷ 2 = 7,616,637.5
If the quotient is a whole number, then 2 and 7,616,637.5 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 | 15,233,275 | |
| -1 | -15,233,275 |
Now, we try dividing 15,233,275 by 3:
15,233,275 ÷ 3 = 5,077,758.3333
If the quotient is a whole number, then 3 and 5,077,758.3333 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 | 15,233,275 | |
| -1 | -15,233,275 |
Let's try dividing by 4:
15,233,275 ÷ 4 = 3,808,318.75
If the quotient is a whole number, then 4 and 3,808,318.75 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 | 15,233,275 | |
| -1 | 15,233,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 73 | 85 | 365 | 425 | 491 | 1,241 | 1,825 | 2,455 | 6,205 | 8,347 | 12,275 | 31,025 | 35,843 | 41,735 | 179,215 | 208,675 | 609,331 | 896,075 | 3,046,655 | 15,233,275 |
| -1 | -5 | -17 | -25 | -73 | -85 | -365 | -425 | -491 | -1,241 | -1,825 | -2,455 | -6,205 | -8,347 | -12,275 | -31,025 | -35,843 | -41,735 | -179,215 | -208,675 | -609,331 | -896,075 | -3,046,655 | -15,233,275 |
