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 3,148,475, 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 | 3,148,475 | |
| -1 | -3,148,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,148,475.
Example:
1 x 3,148,475 = 3,148,475
and
-1 x -3,148,475 = 3,148,475
Notice both answers equal 3,148,475
With that explanation out of the way, let's continue. Next, we take the number 3,148,475 and divide it by 2:
3,148,475 ÷ 2 = 1,574,237.5
If the quotient is a whole number, then 2 and 1,574,237.5 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 | 3,148,475 | |
| -1 | -3,148,475 |
Now, we try dividing 3,148,475 by 3:
3,148,475 ÷ 3 = 1,049,491.6667
If the quotient is a whole number, then 3 and 1,049,491.6667 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 | 3,148,475 | |
| -1 | -3,148,475 |
Let's try dividing by 4:
3,148,475 ÷ 4 = 787,118.75
If the quotient is a whole number, then 4 and 787,118.75 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 | 3,148,475 | |
| -1 | 3,148,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 107 | 275 | 535 | 1,177 | 2,675 | 5,885 | 11,449 | 29,425 | 57,245 | 125,939 | 286,225 | 629,695 | 3,148,475 |
| -1 | -5 | -11 | -25 | -55 | -107 | -275 | -535 | -1,177 | -2,675 | -5,885 | -11,449 | -29,425 | -57,245 | -125,939 | -286,225 | -629,695 | -3,148,475 |
