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 3,100,895, 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 | 3,100,895 | |
| -1 | -3,100,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,100,895.
Example:
1 x 3,100,895 = 3,100,895
and
-1 x -3,100,895 = 3,100,895
Notice both answers equal 3,100,895
With that explanation out of the way, let's continue. Next, we take the number 3,100,895 and divide it by 2:
3,100,895 ÷ 2 = 1,550,447.5
If the quotient is a whole number, then 2 and 1,550,447.5 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 | 3,100,895 | |
| -1 | -3,100,895 |
Now, we try dividing 3,100,895 by 3:
3,100,895 ÷ 3 = 1,033,631.6667
If the quotient is a whole number, then 3 and 1,033,631.6667 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 | 3,100,895 | |
| -1 | -3,100,895 |
Let's try dividing by 4:
3,100,895 ÷ 4 = 775,223.75
If the quotient is a whole number, then 4 and 775,223.75 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 | 3,100,895 | |
| -1 | 3,100,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 4,663 | 23,315 | 32,641 | 88,597 | 163,205 | 442,985 | 620,179 | 3,100,895 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -4,663 | -23,315 | -32,641 | -88,597 | -163,205 | -442,985 | -620,179 | -3,100,895 |
