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 154,666,105, 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 | 154,666,105 | |
| -1 | -154,666,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,666,105.
Example:
1 x 154,666,105 = 154,666,105
and
-1 x -154,666,105 = 154,666,105
Notice both answers equal 154,666,105
With that explanation out of the way, let's continue. Next, we take the number 154,666,105 and divide it by 2:
154,666,105 ÷ 2 = 77,333,052.5
If the quotient is a whole number, then 2 and 77,333,052.5 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 | 154,666,105 | |
| -1 | -154,666,105 |
Now, we try dividing 154,666,105 by 3:
154,666,105 ÷ 3 = 51,555,368.3333
If the quotient is a whole number, then 3 and 51,555,368.3333 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 | 154,666,105 | |
| -1 | -154,666,105 |
Let's try dividing by 4:
154,666,105 ÷ 4 = 38,666,526.25
If the quotient is a whole number, then 4 and 38,666,526.25 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 | 154,666,105 | |
| -1 | 154,666,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 76,003 | 380,015 | 836,033 | 2,812,111 | 4,180,165 | 14,060,555 | 30,933,221 | 154,666,105 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -76,003 | -380,015 | -836,033 | -2,812,111 | -4,180,165 | -14,060,555 | -30,933,221 | -154,666,105 |
