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 12,275,425, 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 | 12,275,425 | |
| -1 | -12,275,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,275,425.
Example:
1 x 12,275,425 = 12,275,425
and
-1 x -12,275,425 = 12,275,425
Notice both answers equal 12,275,425
With that explanation out of the way, let's continue. Next, we take the number 12,275,425 and divide it by 2:
12,275,425 ÷ 2 = 6,137,712.5
If the quotient is a whole number, then 2 and 6,137,712.5 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 | 12,275,425 | |
| -1 | -12,275,425 |
Now, we try dividing 12,275,425 by 3:
12,275,425 ÷ 3 = 4,091,808.3333
If the quotient is a whole number, then 3 and 4,091,808.3333 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 | 12,275,425 | |
| -1 | -12,275,425 |
Let's try dividing by 4:
12,275,425 ÷ 4 = 3,068,856.25
If the quotient is a whole number, then 4 and 3,068,856.25 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 | 12,275,425 | |
| -1 | 12,275,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 43 | 95 | 215 | 475 | 601 | 817 | 1,075 | 3,005 | 4,085 | 11,419 | 15,025 | 20,425 | 25,843 | 57,095 | 129,215 | 285,475 | 491,017 | 646,075 | 2,455,085 | 12,275,425 |
| -1 | -5 | -19 | -25 | -43 | -95 | -215 | -475 | -601 | -817 | -1,075 | -3,005 | -4,085 | -11,419 | -15,025 | -20,425 | -25,843 | -57,095 | -129,215 | -285,475 | -491,017 | -646,075 | -2,455,085 | -12,275,425 |
