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 154,624,459, 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 | 154,624,459 | |
| -1 | -154,624,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,624,459.
Example:
1 x 154,624,459 = 154,624,459
and
-1 x -154,624,459 = 154,624,459
Notice both answers equal 154,624,459
With that explanation out of the way, let's continue. Next, we take the number 154,624,459 and divide it by 2:
154,624,459 ÷ 2 = 77,312,229.5
If the quotient is a whole number, then 2 and 77,312,229.5 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 | 154,624,459 | |
| -1 | -154,624,459 |
Now, we try dividing 154,624,459 by 3:
154,624,459 ÷ 3 = 51,541,486.3333
If the quotient is a whole number, then 3 and 51,541,486.3333 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 | 154,624,459 | |
| -1 | -154,624,459 |
Let's try dividing by 4:
154,624,459 ÷ 4 = 38,656,114.75
If the quotient is a whole number, then 4 and 38,656,114.75 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 | 154,624,459 | |
| -1 | 154,624,459 |
If you did it right, you will end up with this table:
| 1 | 11 | 173 | 193 | 421 | 1,903 | 2,123 | 4,631 | 33,389 | 72,833 | 81,253 | 367,279 | 801,163 | 893,783 | 14,056,769 | 154,624,459 |
| -1 | -11 | -173 | -193 | -421 | -1,903 | -2,123 | -4,631 | -33,389 | -72,833 | -81,253 | -367,279 | -801,163 | -893,783 | -14,056,769 | -154,624,459 |
