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 7,475,495, 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 | 7,475,495 | |
| -1 | -7,475,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,475,495.
Example:
1 x 7,475,495 = 7,475,495
and
-1 x -7,475,495 = 7,475,495
Notice both answers equal 7,475,495
With that explanation out of the way, let's continue. Next, we take the number 7,475,495 and divide it by 2:
7,475,495 ÷ 2 = 3,737,747.5
If the quotient is a whole number, then 2 and 3,737,747.5 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 | 7,475,495 | |
| -1 | -7,475,495 |
Now, we try dividing 7,475,495 by 3:
7,475,495 ÷ 3 = 2,491,831.6667
If the quotient is a whole number, then 3 and 2,491,831.6667 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 | 7,475,495 | |
| -1 | -7,475,495 |
Let's try dividing by 4:
7,475,495 ÷ 4 = 1,868,873.75
If the quotient is a whole number, then 4 and 1,868,873.75 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 | 7,475,495 | |
| -1 | 7,475,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 2,837 | 14,185 | 48,229 | 87,947 | 241,145 | 439,735 | 1,495,099 | 7,475,495 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -2,837 | -14,185 | -48,229 | -87,947 | -241,145 | -439,735 | -1,495,099 | -7,475,495 |
