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 442,420,223, 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 | 442,420,223 | |
| -1 | -442,420,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 442,420,223.
Example:
1 x 442,420,223 = 442,420,223
and
-1 x -442,420,223 = 442,420,223
Notice both answers equal 442,420,223
With that explanation out of the way, let's continue. Next, we take the number 442,420,223 and divide it by 2:
442,420,223 ÷ 2 = 221,210,111.5
If the quotient is a whole number, then 2 and 221,210,111.5 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 | 442,420,223 | |
| -1 | -442,420,223 |
Now, we try dividing 442,420,223 by 3:
442,420,223 ÷ 3 = 147,473,407.6667
If the quotient is a whole number, then 3 and 147,473,407.6667 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 | 442,420,223 | |
| -1 | -442,420,223 |
Let's try dividing by 4:
442,420,223 ÷ 4 = 110,605,055.75
If the quotient is a whole number, then 4 and 110,605,055.75 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 | 442,420,223 | |
| -1 | 442,420,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 73 | 119 | 511 | 1,241 | 8,687 | 50,929 | 356,503 | 865,793 | 3,717,817 | 6,060,551 | 26,024,719 | 63,202,889 | 442,420,223 |
| -1 | -7 | -17 | -73 | -119 | -511 | -1,241 | -8,687 | -50,929 | -356,503 | -865,793 | -3,717,817 | -6,060,551 | -26,024,719 | -63,202,889 | -442,420,223 |
