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 162,647,045, 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 | 162,647,045 | |
| -1 | -162,647,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,647,045.
Example:
1 x 162,647,045 = 162,647,045
and
-1 x -162,647,045 = 162,647,045
Notice both answers equal 162,647,045
With that explanation out of the way, let's continue. Next, we take the number 162,647,045 and divide it by 2:
162,647,045 ÷ 2 = 81,323,522.5
If the quotient is a whole number, then 2 and 81,323,522.5 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 | 162,647,045 | |
| -1 | -162,647,045 |
Now, we try dividing 162,647,045 by 3:
162,647,045 ÷ 3 = 54,215,681.6667
If the quotient is a whole number, then 3 and 54,215,681.6667 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 | 162,647,045 | |
| -1 | -162,647,045 |
Let's try dividing by 4:
162,647,045 ÷ 4 = 40,661,761.25
If the quotient is a whole number, then 4 and 40,661,761.25 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 | 162,647,045 | |
| -1 | 162,647,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 48,479 | 242,395 | 533,269 | 2,666,345 | 2,957,219 | 14,786,095 | 32,529,409 | 162,647,045 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -48,479 | -242,395 | -533,269 | -2,666,345 | -2,957,219 | -14,786,095 | -32,529,409 | -162,647,045 |
