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 163,365,443, 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 | 163,365,443 | |
| -1 | -163,365,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,365,443.
Example:
1 x 163,365,443 = 163,365,443
and
-1 x -163,365,443 = 163,365,443
Notice both answers equal 163,365,443
With that explanation out of the way, let's continue. Next, we take the number 163,365,443 and divide it by 2:
163,365,443 ÷ 2 = 81,682,721.5
If the quotient is a whole number, then 2 and 81,682,721.5 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 | 163,365,443 | |
| -1 | -163,365,443 |
Now, we try dividing 163,365,443 by 3:
163,365,443 ÷ 3 = 54,455,147.6667
If the quotient is a whole number, then 3 and 54,455,147.6667 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 | 163,365,443 | |
| -1 | -163,365,443 |
Let's try dividing by 4:
163,365,443 ÷ 4 = 40,841,360.75
If the quotient is a whole number, then 4 and 40,841,360.75 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 | 163,365,443 | |
| -1 | 163,365,443 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 79 | 1,271 | 1,627 | 2,449 | 3,239 | 50,437 | 66,707 | 100,409 | 128,533 | 2,067,917 | 3,984,523 | 5,269,853 | 163,365,443 |
| -1 | -31 | -41 | -79 | -1,271 | -1,627 | -2,449 | -3,239 | -50,437 | -66,707 | -100,409 | -128,533 | -2,067,917 | -3,984,523 | -5,269,853 | -163,365,443 |
