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 1,225,525, 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 | 1,225,525 | |
| -1 | -1,225,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,225,525.
Example:
1 x 1,225,525 = 1,225,525
and
-1 x -1,225,525 = 1,225,525
Notice both answers equal 1,225,525
With that explanation out of the way, let's continue. Next, we take the number 1,225,525 and divide it by 2:
1,225,525 ÷ 2 = 612,762.5
If the quotient is a whole number, then 2 and 612,762.5 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 | 1,225,525 | |
| -1 | -1,225,525 |
Now, we try dividing 1,225,525 by 3:
1,225,525 ÷ 3 = 408,508.3333
If the quotient is a whole number, then 3 and 408,508.3333 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 | 1,225,525 | |
| -1 | -1,225,525 |
Let's try dividing by 4:
1,225,525 ÷ 4 = 306,381.25
If the quotient is a whole number, then 4 and 306,381.25 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 | 1,225,525 | |
| -1 | 1,225,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 47 | 149 | 175 | 235 | 329 | 745 | 1,043 | 1,175 | 1,645 | 3,725 | 5,215 | 7,003 | 8,225 | 26,075 | 35,015 | 49,021 | 175,075 | 245,105 | 1,225,525 |
| -1 | -5 | -7 | -25 | -35 | -47 | -149 | -175 | -235 | -329 | -745 | -1,043 | -1,175 | -1,645 | -3,725 | -5,215 | -7,003 | -8,225 | -26,075 | -35,015 | -49,021 | -175,075 | -245,105 | -1,225,525 |
