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 163,763,435, 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 | 163,763,435 | |
| -1 | -163,763,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,763,435.
Example:
1 x 163,763,435 = 163,763,435
and
-1 x -163,763,435 = 163,763,435
Notice both answers equal 163,763,435
With that explanation out of the way, let's continue. Next, we take the number 163,763,435 and divide it by 2:
163,763,435 ÷ 2 = 81,881,717.5
If the quotient is a whole number, then 2 and 81,881,717.5 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 | 163,763,435 | |
| -1 | -163,763,435 |
Now, we try dividing 163,763,435 by 3:
163,763,435 ÷ 3 = 54,587,811.6667
If the quotient is a whole number, then 3 and 54,587,811.6667 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 | 163,763,435 | |
| -1 | -163,763,435 |
Let's try dividing by 4:
163,763,435 ÷ 4 = 40,940,858.75
If the quotient is a whole number, then 4 and 40,940,858.75 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 | 163,763,435 | |
| -1 | 163,763,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 102,673 | 513,365 | 1,129,403 | 2,977,517 | 5,647,015 | 14,887,585 | 32,752,687 | 163,763,435 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -102,673 | -513,365 | -1,129,403 | -2,977,517 | -5,647,015 | -14,887,585 | -32,752,687 | -163,763,435 |
