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 281,764,063, 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 | 281,764,063 | |
| -1 | -281,764,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 281,764,063.
Example:
1 x 281,764,063 = 281,764,063
and
-1 x -281,764,063 = 281,764,063
Notice both answers equal 281,764,063
With that explanation out of the way, let's continue. Next, we take the number 281,764,063 and divide it by 2:
281,764,063 ÷ 2 = 140,882,031.5
If the quotient is a whole number, then 2 and 140,882,031.5 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 | 281,764,063 | |
| -1 | -281,764,063 |
Now, we try dividing 281,764,063 by 3:
281,764,063 ÷ 3 = 93,921,354.3333
If the quotient is a whole number, then 3 and 93,921,354.3333 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 | 281,764,063 | |
| -1 | -281,764,063 |
Let's try dividing by 4:
281,764,063 ÷ 4 = 70,441,015.75
If the quotient is a whole number, then 4 and 70,441,015.75 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 | 281,764,063 | |
| -1 | 281,764,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 61 | 107 | 427 | 749 | 881 | 2,989 | 5,243 | 6,167 | 6,527 | 43,169 | 45,689 | 53,741 | 94,267 | 319,823 | 376,187 | 659,869 | 2,633,309 | 4,619,083 | 5,750,287 | 40,252,009 | 281,764,063 |
| -1 | -7 | -49 | -61 | -107 | -427 | -749 | -881 | -2,989 | -5,243 | -6,167 | -6,527 | -43,169 | -45,689 | -53,741 | -94,267 | -319,823 | -376,187 | -659,869 | -2,633,309 | -4,619,083 | -5,750,287 | -40,252,009 | -281,764,063 |
