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 3,113,125, 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 | 3,113,125 | |
| -1 | -3,113,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,113,125.
Example:
1 x 3,113,125 = 3,113,125
and
-1 x -3,113,125 = 3,113,125
Notice both answers equal 3,113,125
With that explanation out of the way, let's continue. Next, we take the number 3,113,125 and divide it by 2:
3,113,125 ÷ 2 = 1,556,562.5
If the quotient is a whole number, then 2 and 1,556,562.5 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 | 3,113,125 | |
| -1 | -3,113,125 |
Now, we try dividing 3,113,125 by 3:
3,113,125 ÷ 3 = 1,037,708.3333
If the quotient is a whole number, then 3 and 1,037,708.3333 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 | 3,113,125 | |
| -1 | -3,113,125 |
Let's try dividing by 4:
3,113,125 ÷ 4 = 778,281.25
If the quotient is a whole number, then 4 and 778,281.25 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 | 3,113,125 | |
| -1 | 3,113,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 293 | 425 | 625 | 1,465 | 2,125 | 4,981 | 7,325 | 10,625 | 24,905 | 36,625 | 124,525 | 183,125 | 622,625 | 3,113,125 |
| -1 | -5 | -17 | -25 | -85 | -125 | -293 | -425 | -625 | -1,465 | -2,125 | -4,981 | -7,325 | -10,625 | -24,905 | -36,625 | -124,525 | -183,125 | -622,625 | -3,113,125 |
