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 154,822,085, 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 | 154,822,085 | |
| -1 | -154,822,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,822,085.
Example:
1 x 154,822,085 = 154,822,085
and
-1 x -154,822,085 = 154,822,085
Notice both answers equal 154,822,085
With that explanation out of the way, let's continue. Next, we take the number 154,822,085 and divide it by 2:
154,822,085 ÷ 2 = 77,411,042.5
If the quotient is a whole number, then 2 and 77,411,042.5 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 | 154,822,085 | |
| -1 | -154,822,085 |
Now, we try dividing 154,822,085 by 3:
154,822,085 ÷ 3 = 51,607,361.6667
If the quotient is a whole number, then 3 and 51,607,361.6667 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 | 154,822,085 | |
| -1 | -154,822,085 |
Let's try dividing by 4:
154,822,085 ÷ 4 = 38,705,521.25
If the quotient is a whole number, then 4 and 38,705,521.25 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 | 154,822,085 | |
| -1 | 154,822,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 122,389 | 611,945 | 1,346,279 | 2,814,947 | 6,731,395 | 14,074,735 | 30,964,417 | 154,822,085 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -122,389 | -611,945 | -1,346,279 | -2,814,947 | -6,731,395 | -14,074,735 | -30,964,417 | -154,822,085 |
