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 154,303,009, 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 | 154,303,009 | |
| -1 | -154,303,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,303,009.
Example:
1 x 154,303,009 = 154,303,009
and
-1 x -154,303,009 = 154,303,009
Notice both answers equal 154,303,009
With that explanation out of the way, let's continue. Next, we take the number 154,303,009 and divide it by 2:
154,303,009 ÷ 2 = 77,151,504.5
If the quotient is a whole number, then 2 and 77,151,504.5 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 | 154,303,009 | |
| -1 | -154,303,009 |
Now, we try dividing 154,303,009 by 3:
154,303,009 ÷ 3 = 51,434,336.3333
If the quotient is a whole number, then 3 and 51,434,336.3333 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 | 154,303,009 | |
| -1 | -154,303,009 |
Let's try dividing by 4:
154,303,009 ÷ 4 = 38,575,752.25
If the quotient is a whole number, then 4 and 38,575,752.25 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 | 154,303,009 | |
| -1 | 154,303,009 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 343 | 931 | 6,517 | 23,677 | 165,739 | 449,863 | 1,160,173 | 3,149,041 | 8,121,211 | 22,043,287 | 154,303,009 |
| -1 | -7 | -19 | -49 | -133 | -343 | -931 | -6,517 | -23,677 | -165,739 | -449,863 | -1,160,173 | -3,149,041 | -8,121,211 | -22,043,287 | -154,303,009 |
