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 224,421,131, 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 | 224,421,131 | |
| -1 | -224,421,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,421,131.
Example:
1 x 224,421,131 = 224,421,131
and
-1 x -224,421,131 = 224,421,131
Notice both answers equal 224,421,131
With that explanation out of the way, let's continue. Next, we take the number 224,421,131 and divide it by 2:
224,421,131 ÷ 2 = 112,210,565.5
If the quotient is a whole number, then 2 and 112,210,565.5 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 | 224,421,131 | |
| -1 | -224,421,131 |
Now, we try dividing 224,421,131 by 3:
224,421,131 ÷ 3 = 74,807,043.6667
If the quotient is a whole number, then 3 and 74,807,043.6667 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 | 224,421,131 | |
| -1 | -224,421,131 |
Let's try dividing by 4:
224,421,131 ÷ 4 = 56,105,282.75
If the quotient is a whole number, then 4 and 56,105,282.75 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 | 224,421,131 | |
| -1 | 224,421,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 71 | 187 | 781 | 1,207 | 13,277 | 16,903 | 185,933 | 287,351 | 1,200,113 | 3,160,861 | 13,201,243 | 20,401,921 | 224,421,131 |
| -1 | -11 | -17 | -71 | -187 | -781 | -1,207 | -13,277 | -16,903 | -185,933 | -287,351 | -1,200,113 | -3,160,861 | -13,201,243 | -20,401,921 | -224,421,131 |
