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 7,475,875, 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 | 7,475,875 | |
| -1 | -7,475,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,475,875.
Example:
1 x 7,475,875 = 7,475,875
and
-1 x -7,475,875 = 7,475,875
Notice both answers equal 7,475,875
With that explanation out of the way, let's continue. Next, we take the number 7,475,875 and divide it by 2:
7,475,875 ÷ 2 = 3,737,937.5
If the quotient is a whole number, then 2 and 3,737,937.5 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 | 7,475,875 | |
| -1 | -7,475,875 |
Now, we try dividing 7,475,875 by 3:
7,475,875 ÷ 3 = 2,491,958.3333
If the quotient is a whole number, then 3 and 2,491,958.3333 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 | 7,475,875 | |
| -1 | -7,475,875 |
Let's try dividing by 4:
7,475,875 ÷ 4 = 1,868,968.75
If the quotient is a whole number, then 4 and 1,868,968.75 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 | 7,475,875 | |
| -1 | 7,475,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 5,437 | 27,185 | 59,807 | 135,925 | 299,035 | 679,625 | 1,495,175 | 7,475,875 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -5,437 | -27,185 | -59,807 | -135,925 | -299,035 | -679,625 | -1,495,175 | -7,475,875 |
