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 226,560,551, 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 | 226,560,551 | |
| -1 | -226,560,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 226,560,551.
Example:
1 x 226,560,551 = 226,560,551
and
-1 x -226,560,551 = 226,560,551
Notice both answers equal 226,560,551
With that explanation out of the way, let's continue. Next, we take the number 226,560,551 and divide it by 2:
226,560,551 ÷ 2 = 113,280,275.5
If the quotient is a whole number, then 2 and 113,280,275.5 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 | 226,560,551 | |
| -1 | -226,560,551 |
Now, we try dividing 226,560,551 by 3:
226,560,551 ÷ 3 = 75,520,183.6667
If the quotient is a whole number, then 3 and 75,520,183.6667 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 | 226,560,551 | |
| -1 | -226,560,551 |
Let's try dividing by 4:
226,560,551 ÷ 4 = 56,640,137.75
If the quotient is a whole number, then 4 and 56,640,137.75 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 | 226,560,551 | |
| -1 | 226,560,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 151 | 721 | 1,057 | 2,081 | 14,567 | 15,553 | 108,871 | 214,343 | 314,231 | 1,500,401 | 2,199,617 | 32,365,793 | 226,560,551 |
| -1 | -7 | -103 | -151 | -721 | -1,057 | -2,081 | -14,567 | -15,553 | -108,871 | -214,343 | -314,231 | -1,500,401 | -2,199,617 | -32,365,793 | -226,560,551 |
