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 162,543,053, 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 | 162,543,053 | |
| -1 | -162,543,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,543,053.
Example:
1 x 162,543,053 = 162,543,053
and
-1 x -162,543,053 = 162,543,053
Notice both answers equal 162,543,053
With that explanation out of the way, let's continue. Next, we take the number 162,543,053 and divide it by 2:
162,543,053 ÷ 2 = 81,271,526.5
If the quotient is a whole number, then 2 and 81,271,526.5 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 | 162,543,053 | |
| -1 | -162,543,053 |
Now, we try dividing 162,543,053 by 3:
162,543,053 ÷ 3 = 54,181,017.6667
If the quotient is a whole number, then 3 and 54,181,017.6667 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 | 162,543,053 | |
| -1 | -162,543,053 |
Let's try dividing by 4:
162,543,053 ÷ 4 = 40,635,763.25
If the quotient is a whole number, then 4 and 40,635,763.25 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 | 162,543,053 | |
| -1 | 162,543,053 |
If you did it right, you will end up with this table:
| 1 | 43 | 59 | 79 | 811 | 2,537 | 3,397 | 4,661 | 34,873 | 47,849 | 64,069 | 200,423 | 2,057,507 | 2,754,967 | 3,780,071 | 162,543,053 |
| -1 | -43 | -59 | -79 | -811 | -2,537 | -3,397 | -4,661 | -34,873 | -47,849 | -64,069 | -200,423 | -2,057,507 | -2,754,967 | -3,780,071 | -162,543,053 |
