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 452,647,145, 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 | 452,647,145 | |
| -1 | -452,647,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 452,647,145.
Example:
1 x 452,647,145 = 452,647,145
and
-1 x -452,647,145 = 452,647,145
Notice both answers equal 452,647,145
With that explanation out of the way, let's continue. Next, we take the number 452,647,145 and divide it by 2:
452,647,145 ÷ 2 = 226,323,572.5
If the quotient is a whole number, then 2 and 226,323,572.5 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 | 452,647,145 | |
| -1 | -452,647,145 |
Now, we try dividing 452,647,145 by 3:
452,647,145 ÷ 3 = 150,882,381.6667
If the quotient is a whole number, then 3 and 150,882,381.6667 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 | 452,647,145 | |
| -1 | -452,647,145 |
Let's try dividing by 4:
452,647,145 ÷ 4 = 113,161,786.25
If the quotient is a whole number, then 4 and 113,161,786.25 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 | 452,647,145 | |
| -1 | 452,647,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 179 | 305 | 895 | 8,291 | 10,919 | 41,455 | 54,595 | 505,751 | 1,484,089 | 2,528,755 | 7,420,445 | 90,529,429 | 452,647,145 |
| -1 | -5 | -61 | -179 | -305 | -895 | -8,291 | -10,919 | -41,455 | -54,595 | -505,751 | -1,484,089 | -2,528,755 | -7,420,445 | -90,529,429 | -452,647,145 |
