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 225,301,445, 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 | 225,301,445 | |
| -1 | -225,301,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,301,445.
Example:
1 x 225,301,445 = 225,301,445
and
-1 x -225,301,445 = 225,301,445
Notice both answers equal 225,301,445
With that explanation out of the way, let's continue. Next, we take the number 225,301,445 and divide it by 2:
225,301,445 ÷ 2 = 112,650,722.5
If the quotient is a whole number, then 2 and 112,650,722.5 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 | 225,301,445 | |
| -1 | -225,301,445 |
Now, we try dividing 225,301,445 by 3:
225,301,445 ÷ 3 = 75,100,481.6667
If the quotient is a whole number, then 3 and 75,100,481.6667 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 | 225,301,445 | |
| -1 | -225,301,445 |
Let's try dividing by 4:
225,301,445 ÷ 4 = 56,325,361.25
If the quotient is a whole number, then 4 and 56,325,361.25 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 | 225,301,445 | |
| -1 | 225,301,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 193 | 965 | 4,439 | 10,151 | 22,195 | 50,755 | 233,473 | 1,167,365 | 1,959,143 | 9,795,715 | 45,060,289 | 225,301,445 |
| -1 | -5 | -23 | -115 | -193 | -965 | -4,439 | -10,151 | -22,195 | -50,755 | -233,473 | -1,167,365 | -1,959,143 | -9,795,715 | -45,060,289 | -225,301,445 |
