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 281,766,359, 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 | 281,766,359 | |
| -1 | -281,766,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 281,766,359.
Example:
1 x 281,766,359 = 281,766,359
and
-1 x -281,766,359 = 281,766,359
Notice both answers equal 281,766,359
With that explanation out of the way, let's continue. Next, we take the number 281,766,359 and divide it by 2:
281,766,359 ÷ 2 = 140,883,179.5
If the quotient is a whole number, then 2 and 140,883,179.5 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 | 281,766,359 | |
| -1 | -281,766,359 |
Now, we try dividing 281,766,359 by 3:
281,766,359 ÷ 3 = 93,922,119.6667
If the quotient is a whole number, then 3 and 93,922,119.6667 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 | 281,766,359 | |
| -1 | -281,766,359 |
Let's try dividing by 4:
281,766,359 ÷ 4 = 70,441,589.75
If the quotient is a whole number, then 4 and 70,441,589.75 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 | 281,766,359 | |
| -1 | 281,766,359 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 59 | 259 | 413 | 2,183 | 15,281 | 18,439 | 129,073 | 682,243 | 1,087,901 | 4,775,701 | 7,615,307 | 40,252,337 | 281,766,359 |
| -1 | -7 | -37 | -59 | -259 | -413 | -2,183 | -15,281 | -18,439 | -129,073 | -682,243 | -1,087,901 | -4,775,701 | -7,615,307 | -40,252,337 | -281,766,359 |
