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 446,132,315, 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 | 446,132,315 | |
| -1 | -446,132,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 446,132,315.
Example:
1 x 446,132,315 = 446,132,315
and
-1 x -446,132,315 = 446,132,315
Notice both answers equal 446,132,315
With that explanation out of the way, let's continue. Next, we take the number 446,132,315 and divide it by 2:
446,132,315 ÷ 2 = 223,066,157.5
If the quotient is a whole number, then 2 and 223,066,157.5 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 | 446,132,315 | |
| -1 | -446,132,315 |
Now, we try dividing 446,132,315 by 3:
446,132,315 ÷ 3 = 148,710,771.6667
If the quotient is a whole number, then 3 and 148,710,771.6667 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 | 446,132,315 | |
| -1 | -446,132,315 |
Let's try dividing by 4:
446,132,315 ÷ 4 = 111,533,078.75
If the quotient is a whole number, then 4 and 111,533,078.75 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 | 446,132,315 | |
| -1 | 446,132,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 139 | 155 | 695 | 4,309 | 20,707 | 21,545 | 103,535 | 641,917 | 2,878,273 | 3,209,585 | 14,391,365 | 89,226,463 | 446,132,315 |
| -1 | -5 | -31 | -139 | -155 | -695 | -4,309 | -20,707 | -21,545 | -103,535 | -641,917 | -2,878,273 | -3,209,585 | -14,391,365 | -89,226,463 | -446,132,315 |
