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 15,152,375, 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 | 15,152,375 | |
| -1 | -15,152,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,152,375.
Example:
1 x 15,152,375 = 15,152,375
and
-1 x -15,152,375 = 15,152,375
Notice both answers equal 15,152,375
With that explanation out of the way, let's continue. Next, we take the number 15,152,375 and divide it by 2:
15,152,375 ÷ 2 = 7,576,187.5
If the quotient is a whole number, then 2 and 7,576,187.5 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 | 15,152,375 | |
| -1 | -15,152,375 |
Now, we try dividing 15,152,375 by 3:
15,152,375 ÷ 3 = 5,050,791.6667
If the quotient is a whole number, then 3 and 5,050,791.6667 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 | 15,152,375 | |
| -1 | -15,152,375 |
Let's try dividing by 4:
15,152,375 ÷ 4 = 3,788,093.75
If the quotient is a whole number, then 4 and 3,788,093.75 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 | 15,152,375 | |
| -1 | 15,152,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 17,317 | 86,585 | 121,219 | 432,925 | 606,095 | 2,164,625 | 3,030,475 | 15,152,375 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -17,317 | -86,585 | -121,219 | -432,925 | -606,095 | -2,164,625 | -3,030,475 | -15,152,375 |
