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 446,620,517, 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 | 446,620,517 | |
| -1 | -446,620,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 446,620,517.
Example:
1 x 446,620,517 = 446,620,517
and
-1 x -446,620,517 = 446,620,517
Notice both answers equal 446,620,517
With that explanation out of the way, let's continue. Next, we take the number 446,620,517 and divide it by 2:
446,620,517 ÷ 2 = 223,310,258.5
If the quotient is a whole number, then 2 and 223,310,258.5 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 | 446,620,517 | |
| -1 | -446,620,517 |
Now, we try dividing 446,620,517 by 3:
446,620,517 ÷ 3 = 148,873,505.6667
If the quotient is a whole number, then 3 and 148,873,505.6667 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 | 446,620,517 | |
| -1 | -446,620,517 |
Let's try dividing by 4:
446,620,517 ÷ 4 = 111,655,129.25
If the quotient is a whole number, then 4 and 111,655,129.25 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 | 446,620,517 | |
| -1 | 446,620,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 883 | 3,803 | 6,181 | 16,777 | 26,621 | 72,257 | 117,439 | 505,799 | 3,358,049 | 23,506,343 | 63,802,931 | 446,620,517 |
| -1 | -7 | -19 | -133 | -883 | -3,803 | -6,181 | -16,777 | -26,621 | -72,257 | -117,439 | -505,799 | -3,358,049 | -23,506,343 | -63,802,931 | -446,620,517 |
