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 228,536,125, 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 | 228,536,125 | |
| -1 | -228,536,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,536,125.
Example:
1 x 228,536,125 = 228,536,125
and
-1 x -228,536,125 = 228,536,125
Notice both answers equal 228,536,125
With that explanation out of the way, let's continue. Next, we take the number 228,536,125 and divide it by 2:
228,536,125 ÷ 2 = 114,268,062.5
If the quotient is a whole number, then 2 and 114,268,062.5 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 | 228,536,125 | |
| -1 | -228,536,125 |
Now, we try dividing 228,536,125 by 3:
228,536,125 ÷ 3 = 76,178,708.3333
If the quotient is a whole number, then 3 and 76,178,708.3333 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 | 228,536,125 | |
| -1 | -228,536,125 |
Let's try dividing by 4:
228,536,125 ÷ 4 = 57,134,031.25
If the quotient is a whole number, then 4 and 57,134,031.25 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 | 228,536,125 | |
| -1 | 228,536,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 193 | 965 | 4,825 | 9,473 | 24,125 | 47,365 | 236,825 | 1,184,125 | 1,828,289 | 9,141,445 | 45,707,225 | 228,536,125 |
| -1 | -5 | -25 | -125 | -193 | -965 | -4,825 | -9,473 | -24,125 | -47,365 | -236,825 | -1,184,125 | -1,828,289 | -9,141,445 | -45,707,225 | -228,536,125 |
