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 481,121,281, 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 | 481,121,281 | |
| -1 | -481,121,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 481,121,281.
Example:
1 x 481,121,281 = 481,121,281
and
-1 x -481,121,281 = 481,121,281
Notice both answers equal 481,121,281
With that explanation out of the way, let's continue. Next, we take the number 481,121,281 and divide it by 2:
481,121,281 ÷ 2 = 240,560,640.5
If the quotient is a whole number, then 2 and 240,560,640.5 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 | 481,121,281 | |
| -1 | -481,121,281 |
Now, we try dividing 481,121,281 by 3:
481,121,281 ÷ 3 = 160,373,760.3333
If the quotient is a whole number, then 3 and 160,373,760.3333 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 | 481,121,281 | |
| -1 | -481,121,281 |
Let's try dividing by 4:
481,121,281 ÷ 4 = 120,280,320.25
If the quotient is a whole number, then 4 and 120,280,320.25 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 | 481,121,281 | |
| -1 | 481,121,281 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 47 | 1,247 | 1,363 | 2,021 | 8,209 | 58,609 | 238,061 | 352,987 | 385,823 | 10,236,623 | 11,188,867 | 16,590,389 | 481,121,281 |
| -1 | -29 | -43 | -47 | -1,247 | -1,363 | -2,021 | -8,209 | -58,609 | -238,061 | -352,987 | -385,823 | -10,236,623 | -11,188,867 | -16,590,389 | -481,121,281 |
