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 3,311,525, 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 | 3,311,525 | |
| -1 | -3,311,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,311,525.
Example:
1 x 3,311,525 = 3,311,525
and
-1 x -3,311,525 = 3,311,525
Notice both answers equal 3,311,525
With that explanation out of the way, let's continue. Next, we take the number 3,311,525 and divide it by 2:
3,311,525 ÷ 2 = 1,655,762.5
If the quotient is a whole number, then 2 and 1,655,762.5 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 | 3,311,525 | |
| -1 | -3,311,525 |
Now, we try dividing 3,311,525 by 3:
3,311,525 ÷ 3 = 1,103,841.6667
If the quotient is a whole number, then 3 and 1,103,841.6667 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 | 3,311,525 | |
| -1 | -3,311,525 |
Let's try dividing by 4:
3,311,525 ÷ 4 = 827,881.25
If the quotient is a whole number, then 4 and 827,881.25 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 | 3,311,525 | |
| -1 | 3,311,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 127 | 149 | 175 | 635 | 745 | 889 | 1,043 | 3,175 | 3,725 | 4,445 | 5,215 | 18,923 | 22,225 | 26,075 | 94,615 | 132,461 | 473,075 | 662,305 | 3,311,525 |
| -1 | -5 | -7 | -25 | -35 | -127 | -149 | -175 | -635 | -745 | -889 | -1,043 | -3,175 | -3,725 | -4,445 | -5,215 | -18,923 | -22,225 | -26,075 | -94,615 | -132,461 | -473,075 | -662,305 | -3,311,525 |
