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 162,258,307, 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 | 162,258,307 | |
| -1 | -162,258,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,258,307.
Example:
1 x 162,258,307 = 162,258,307
and
-1 x -162,258,307 = 162,258,307
Notice both answers equal 162,258,307
With that explanation out of the way, let's continue. Next, we take the number 162,258,307 and divide it by 2:
162,258,307 ÷ 2 = 81,129,153.5
If the quotient is a whole number, then 2 and 81,129,153.5 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 | 162,258,307 | |
| -1 | -162,258,307 |
Now, we try dividing 162,258,307 by 3:
162,258,307 ÷ 3 = 54,086,102.3333
If the quotient is a whole number, then 3 and 54,086,102.3333 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 | 162,258,307 | |
| -1 | -162,258,307 |
Let's try dividing by 4:
162,258,307 ÷ 4 = 40,564,576.75
If the quotient is a whole number, then 4 and 40,564,576.75 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 | 162,258,307 | |
| -1 | 162,258,307 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 359 | 457 | 989 | 8,257 | 10,511 | 15,437 | 19,651 | 164,063 | 355,051 | 451,973 | 3,773,449 | 7,054,709 | 162,258,307 |
| -1 | -23 | -43 | -359 | -457 | -989 | -8,257 | -10,511 | -15,437 | -19,651 | -164,063 | -355,051 | -451,973 | -3,773,449 | -7,054,709 | -162,258,307 |
