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 163,344,545, 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 | 163,344,545 | |
| -1 | -163,344,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,344,545.
Example:
1 x 163,344,545 = 163,344,545
and
-1 x -163,344,545 = 163,344,545
Notice both answers equal 163,344,545
With that explanation out of the way, let's continue. Next, we take the number 163,344,545 and divide it by 2:
163,344,545 ÷ 2 = 81,672,272.5
If the quotient is a whole number, then 2 and 81,672,272.5 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 | 163,344,545 | |
| -1 | -163,344,545 |
Now, we try dividing 163,344,545 by 3:
163,344,545 ÷ 3 = 54,448,181.6667
If the quotient is a whole number, then 3 and 54,448,181.6667 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 | 163,344,545 | |
| -1 | -163,344,545 |
Let's try dividing by 4:
163,344,545 ÷ 4 = 40,836,136.25
If the quotient is a whole number, then 4 and 40,836,136.25 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 | 163,344,545 | |
| -1 | 163,344,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 358,999 | 1,794,995 | 2,512,993 | 4,666,987 | 12,564,965 | 23,334,935 | 32,668,909 | 163,344,545 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -358,999 | -1,794,995 | -2,512,993 | -4,666,987 | -12,564,965 | -23,334,935 | -32,668,909 | -163,344,545 |
