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 3,112,525, 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 | 3,112,525 | |
| -1 | -3,112,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,112,525.
Example:
1 x 3,112,525 = 3,112,525
and
-1 x -3,112,525 = 3,112,525
Notice both answers equal 3,112,525
With that explanation out of the way, let's continue. Next, we take the number 3,112,525 and divide it by 2:
3,112,525 ÷ 2 = 1,556,262.5
If the quotient is a whole number, then 2 and 1,556,262.5 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 | 3,112,525 | |
| -1 | -3,112,525 |
Now, we try dividing 3,112,525 by 3:
3,112,525 ÷ 3 = 1,037,508.3333
If the quotient is a whole number, then 3 and 1,037,508.3333 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 | 3,112,525 | |
| -1 | -3,112,525 |
Let's try dividing by 4:
3,112,525 ÷ 4 = 778,131.25
If the quotient is a whole number, then 4 and 778,131.25 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 | 3,112,525 | |
| -1 | 3,112,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 61 | 65 | 157 | 305 | 325 | 785 | 793 | 1,525 | 2,041 | 3,925 | 3,965 | 9,577 | 10,205 | 19,825 | 47,885 | 51,025 | 124,501 | 239,425 | 622,505 | 3,112,525 |
| -1 | -5 | -13 | -25 | -61 | -65 | -157 | -305 | -325 | -785 | -793 | -1,525 | -2,041 | -3,925 | -3,965 | -9,577 | -10,205 | -19,825 | -47,885 | -51,025 | -124,501 | -239,425 | -622,505 | -3,112,525 |
