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 3,103,415, 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 | 3,103,415 | |
| -1 | -3,103,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,103,415.
Example:
1 x 3,103,415 = 3,103,415
and
-1 x -3,103,415 = 3,103,415
Notice both answers equal 3,103,415
With that explanation out of the way, let's continue. Next, we take the number 3,103,415 and divide it by 2:
3,103,415 ÷ 2 = 1,551,707.5
If the quotient is a whole number, then 2 and 1,551,707.5 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 | 3,103,415 | |
| -1 | -3,103,415 |
Now, we try dividing 3,103,415 by 3:
3,103,415 ÷ 3 = 1,034,471.6667
If the quotient is a whole number, then 3 and 1,034,471.6667 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 | 3,103,415 | |
| -1 | -3,103,415 |
Let's try dividing by 4:
3,103,415 ÷ 4 = 775,853.75
If the quotient is a whole number, then 4 and 775,853.75 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 | 3,103,415 | |
| -1 | 3,103,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 53 | 239 | 245 | 265 | 371 | 1,195 | 1,673 | 1,855 | 2,597 | 8,365 | 11,711 | 12,667 | 12,985 | 58,555 | 63,335 | 88,669 | 443,345 | 620,683 | 3,103,415 |
| -1 | -5 | -7 | -35 | -49 | -53 | -239 | -245 | -265 | -371 | -1,195 | -1,673 | -1,855 | -2,597 | -8,365 | -11,711 | -12,667 | -12,985 | -58,555 | -63,335 | -88,669 | -443,345 | -620,683 | -3,103,415 |
