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 12,461,425, 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 | 12,461,425 | |
| -1 | -12,461,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,461,425.
Example:
1 x 12,461,425 = 12,461,425
and
-1 x -12,461,425 = 12,461,425
Notice both answers equal 12,461,425
With that explanation out of the way, let's continue. Next, we take the number 12,461,425 and divide it by 2:
12,461,425 ÷ 2 = 6,230,712.5
If the quotient is a whole number, then 2 and 6,230,712.5 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 | 12,461,425 | |
| -1 | -12,461,425 |
Now, we try dividing 12,461,425 by 3:
12,461,425 ÷ 3 = 4,153,808.3333
If the quotient is a whole number, then 3 and 4,153,808.3333 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 | 12,461,425 | |
| -1 | -12,461,425 |
Let's try dividing by 4:
12,461,425 ÷ 4 = 3,115,356.25
If the quotient is a whole number, then 4 and 3,115,356.25 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 | 12,461,425 | |
| -1 | 12,461,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 109 | 269 | 425 | 545 | 1,345 | 1,853 | 2,725 | 4,573 | 6,725 | 9,265 | 22,865 | 29,321 | 46,325 | 114,325 | 146,605 | 498,457 | 733,025 | 2,492,285 | 12,461,425 |
| -1 | -5 | -17 | -25 | -85 | -109 | -269 | -425 | -545 | -1,345 | -1,853 | -2,725 | -4,573 | -6,725 | -9,265 | -22,865 | -29,321 | -46,325 | -114,325 | -146,605 | -498,457 | -733,025 | -2,492,285 | -12,461,425 |
