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 165,669,341, 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 | 165,669,341 | |
| -1 | -165,669,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,669,341.
Example:
1 x 165,669,341 = 165,669,341
and
-1 x -165,669,341 = 165,669,341
Notice both answers equal 165,669,341
With that explanation out of the way, let's continue. Next, we take the number 165,669,341 and divide it by 2:
165,669,341 ÷ 2 = 82,834,670.5
If the quotient is a whole number, then 2 and 82,834,670.5 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 | 165,669,341 | |
| -1 | -165,669,341 |
Now, we try dividing 165,669,341 by 3:
165,669,341 ÷ 3 = 55,223,113.6667
If the quotient is a whole number, then 3 and 55,223,113.6667 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 | 165,669,341 | |
| -1 | -165,669,341 |
Let's try dividing by 4:
165,669,341 ÷ 4 = 41,417,335.25
If the quotient is a whole number, then 4 and 41,417,335.25 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 | 165,669,341 | |
| -1 | 165,669,341 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 127 | 967 | 1,349 | 2,413 | 9,017 | 18,373 | 68,657 | 122,809 | 171,323 | 1,304,483 | 2,333,371 | 8,719,439 | 165,669,341 |
| -1 | -19 | -71 | -127 | -967 | -1,349 | -2,413 | -9,017 | -18,373 | -68,657 | -122,809 | -171,323 | -1,304,483 | -2,333,371 | -8,719,439 | -165,669,341 |
