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 450,225,307, 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 | 450,225,307 | |
| -1 | -450,225,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 450,225,307.
Example:
1 x 450,225,307 = 450,225,307
and
-1 x -450,225,307 = 450,225,307
Notice both answers equal 450,225,307
With that explanation out of the way, let's continue. Next, we take the number 450,225,307 and divide it by 2:
450,225,307 ÷ 2 = 225,112,653.5
If the quotient is a whole number, then 2 and 225,112,653.5 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 | 450,225,307 | |
| -1 | -450,225,307 |
Now, we try dividing 450,225,307 by 3:
450,225,307 ÷ 3 = 150,075,102.3333
If the quotient is a whole number, then 3 and 150,075,102.3333 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 | 450,225,307 | |
| -1 | -450,225,307 |
Let's try dividing by 4:
450,225,307 ÷ 4 = 112,556,326.75
If the quotient is a whole number, then 4 and 112,556,326.75 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 | 450,225,307 | |
| -1 | 450,225,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 547 | 3,793 | 3,829 | 16,957 | 26,551 | 117,583 | 118,699 | 823,081 | 2,074,771 | 14,523,397 | 64,317,901 | 450,225,307 |
| -1 | -7 | -31 | -217 | -547 | -3,793 | -3,829 | -16,957 | -26,551 | -117,583 | -118,699 | -823,081 | -2,074,771 | -14,523,397 | -64,317,901 | -450,225,307 |
