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 7,504,175, 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 | 7,504,175 | |
| -1 | -7,504,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,504,175.
Example:
1 x 7,504,175 = 7,504,175
and
-1 x -7,504,175 = 7,504,175
Notice both answers equal 7,504,175
With that explanation out of the way, let's continue. Next, we take the number 7,504,175 and divide it by 2:
7,504,175 ÷ 2 = 3,752,087.5
If the quotient is a whole number, then 2 and 3,752,087.5 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 | 7,504,175 | |
| -1 | -7,504,175 |
Now, we try dividing 7,504,175 by 3:
7,504,175 ÷ 3 = 2,501,391.6667
If the quotient is a whole number, then 3 and 2,501,391.6667 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 | 7,504,175 | |
| -1 | -7,504,175 |
Let's try dividing by 4:
7,504,175 ÷ 4 = 1,876,043.75
If the quotient is a whole number, then 4 and 1,876,043.75 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 | 7,504,175 | |
| -1 | 7,504,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 137 | 175 | 313 | 685 | 959 | 1,565 | 2,191 | 3,425 | 4,795 | 7,825 | 10,955 | 23,975 | 42,881 | 54,775 | 214,405 | 300,167 | 1,072,025 | 1,500,835 | 7,504,175 |
| -1 | -5 | -7 | -25 | -35 | -137 | -175 | -313 | -685 | -959 | -1,565 | -2,191 | -3,425 | -4,795 | -7,825 | -10,955 | -23,975 | -42,881 | -54,775 | -214,405 | -300,167 | -1,072,025 | -1,500,835 | -7,504,175 |
