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 228,687,275, 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 | 228,687,275 | |
| -1 | -228,687,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,687,275.
Example:
1 x 228,687,275 = 228,687,275
and
-1 x -228,687,275 = 228,687,275
Notice both answers equal 228,687,275
With that explanation out of the way, let's continue. Next, we take the number 228,687,275 and divide it by 2:
228,687,275 ÷ 2 = 114,343,637.5
If the quotient is a whole number, then 2 and 114,343,637.5 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 | 228,687,275 | |
| -1 | -228,687,275 |
Now, we try dividing 228,687,275 by 3:
228,687,275 ÷ 3 = 76,229,091.6667
If the quotient is a whole number, then 3 and 76,229,091.6667 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 | 228,687,275 | |
| -1 | -228,687,275 |
Let's try dividing by 4:
228,687,275 ÷ 4 = 57,171,818.75
If the quotient is a whole number, then 4 and 57,171,818.75 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 | 228,687,275 | |
| -1 | 228,687,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 463 | 575 | 859 | 2,315 | 4,295 | 10,649 | 11,575 | 19,757 | 21,475 | 53,245 | 98,785 | 266,225 | 397,717 | 493,925 | 1,988,585 | 9,147,491 | 9,942,925 | 45,737,455 | 228,687,275 |
| -1 | -5 | -23 | -25 | -115 | -463 | -575 | -859 | -2,315 | -4,295 | -10,649 | -11,575 | -19,757 | -21,475 | -53,245 | -98,785 | -266,225 | -397,717 | -493,925 | -1,988,585 | -9,147,491 | -9,942,925 | -45,737,455 | -228,687,275 |
