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 443,420,611, 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 | 443,420,611 | |
| -1 | -443,420,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 443,420,611.
Example:
1 x 443,420,611 = 443,420,611
and
-1 x -443,420,611 = 443,420,611
Notice both answers equal 443,420,611
With that explanation out of the way, let's continue. Next, we take the number 443,420,611 and divide it by 2:
443,420,611 ÷ 2 = 221,710,305.5
If the quotient is a whole number, then 2 and 221,710,305.5 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 | 443,420,611 | |
| -1 | -443,420,611 |
Now, we try dividing 443,420,611 by 3:
443,420,611 ÷ 3 = 147,806,870.3333
If the quotient is a whole number, then 3 and 147,806,870.3333 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 | 443,420,611 | |
| -1 | -443,420,611 |
Let's try dividing by 4:
443,420,611 ÷ 4 = 110,855,152.75
If the quotient is a whole number, then 4 and 110,855,152.75 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 | 443,420,611 | |
| -1 | 443,420,611 |
If you did it right, you will end up with this table:
| 1 | 23 | 83 | 109 | 1,909 | 2,131 | 2,507 | 9,047 | 49,013 | 176,873 | 208,081 | 232,279 | 4,068,079 | 5,342,417 | 19,279,157 | 443,420,611 |
| -1 | -23 | -83 | -109 | -1,909 | -2,131 | -2,507 | -9,047 | -49,013 | -176,873 | -208,081 | -232,279 | -4,068,079 | -5,342,417 | -19,279,157 | -443,420,611 |
