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 281,370,383, 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 | 281,370,383 | |
| -1 | -281,370,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 281,370,383.
Example:
1 x 281,370,383 = 281,370,383
and
-1 x -281,370,383 = 281,370,383
Notice both answers equal 281,370,383
With that explanation out of the way, let's continue. Next, we take the number 281,370,383 and divide it by 2:
281,370,383 ÷ 2 = 140,685,191.5
If the quotient is a whole number, then 2 and 140,685,191.5 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 | 281,370,383 | |
| -1 | -281,370,383 |
Now, we try dividing 281,370,383 by 3:
281,370,383 ÷ 3 = 93,790,127.6667
If the quotient is a whole number, then 3 and 93,790,127.6667 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 | 281,370,383 | |
| -1 | -281,370,383 |
Let's try dividing by 4:
281,370,383 ÷ 4 = 70,342,595.75
If the quotient is a whole number, then 4 and 70,342,595.75 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 | 281,370,383 | |
| -1 | 281,370,383 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 493 | 3,451 | 81,533 | 570,731 | 1,386,061 | 2,364,457 | 9,702,427 | 16,551,199 | 40,195,769 | 281,370,383 |
| -1 | -7 | -17 | -29 | -119 | -203 | -493 | -3,451 | -81,533 | -570,731 | -1,386,061 | -2,364,457 | -9,702,427 | -16,551,199 | -40,195,769 | -281,370,383 |
