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 162,345,053, 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 | 162,345,053 | |
| -1 | -162,345,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,345,053.
Example:
1 x 162,345,053 = 162,345,053
and
-1 x -162,345,053 = 162,345,053
Notice both answers equal 162,345,053
With that explanation out of the way, let's continue. Next, we take the number 162,345,053 and divide it by 2:
162,345,053 ÷ 2 = 81,172,526.5
If the quotient is a whole number, then 2 and 81,172,526.5 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 | 162,345,053 | |
| -1 | -162,345,053 |
Now, we try dividing 162,345,053 by 3:
162,345,053 ÷ 3 = 54,115,017.6667
If the quotient is a whole number, then 3 and 54,115,017.6667 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 | 162,345,053 | |
| -1 | -162,345,053 |
Let's try dividing by 4:
162,345,053 ÷ 4 = 40,586,263.25
If the quotient is a whole number, then 4 and 40,586,263.25 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 | 162,345,053 | |
| -1 | 162,345,053 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 353 | 2,081 | 4,589 | 6,001 | 27,053 | 35,377 | 78,013 | 459,901 | 734,593 | 9,549,709 | 12,488,081 | 162,345,053 |
| -1 | -13 | -17 | -221 | -353 | -2,081 | -4,589 | -6,001 | -27,053 | -35,377 | -78,013 | -459,901 | -734,593 | -9,549,709 | -12,488,081 | -162,345,053 |
