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 225,667,145, 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 | 225,667,145 | |
| -1 | -225,667,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,667,145.
Example:
1 x 225,667,145 = 225,667,145
and
-1 x -225,667,145 = 225,667,145
Notice both answers equal 225,667,145
With that explanation out of the way, let's continue. Next, we take the number 225,667,145 and divide it by 2:
225,667,145 ÷ 2 = 112,833,572.5
If the quotient is a whole number, then 2 and 112,833,572.5 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 | 225,667,145 | |
| -1 | -225,667,145 |
Now, we try dividing 225,667,145 by 3:
225,667,145 ÷ 3 = 75,222,381.6667
If the quotient is a whole number, then 3 and 75,222,381.6667 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 | 225,667,145 | |
| -1 | -225,667,145 |
Let's try dividing by 4:
225,667,145 ÷ 4 = 56,416,786.25
If the quotient is a whole number, then 4 and 56,416,786.25 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 | 225,667,145 | |
| -1 | 225,667,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 178,393 | 891,965 | 1,962,323 | 4,103,039 | 9,811,615 | 20,515,195 | 45,133,429 | 225,667,145 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -178,393 | -891,965 | -1,962,323 | -4,103,039 | -9,811,615 | -20,515,195 | -45,133,429 | -225,667,145 |
