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 162,644,545, 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 | 162,644,545 | |
| -1 | -162,644,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,644,545.
Example:
1 x 162,644,545 = 162,644,545
and
-1 x -162,644,545 = 162,644,545
Notice both answers equal 162,644,545
With that explanation out of the way, let's continue. Next, we take the number 162,644,545 and divide it by 2:
162,644,545 ÷ 2 = 81,322,272.5
If the quotient is a whole number, then 2 and 81,322,272.5 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 | 162,644,545 | |
| -1 | -162,644,545 |
Now, we try dividing 162,644,545 by 3:
162,644,545 ÷ 3 = 54,214,848.3333
If the quotient is a whole number, then 3 and 54,214,848.3333 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 | 162,644,545 | |
| -1 | -162,644,545 |
Let's try dividing by 4:
162,644,545 ÷ 4 = 40,661,136.25
If the quotient is a whole number, then 4 and 40,661,136.25 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 | 162,644,545 | |
| -1 | 162,644,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 87,679 | 438,395 | 613,753 | 3,068,765 | 4,646,987 | 23,234,935 | 32,528,909 | 162,644,545 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -87,679 | -438,395 | -613,753 | -3,068,765 | -4,646,987 | -23,234,935 | -32,528,909 | -162,644,545 |
