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 150,117,469, 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 | 150,117,469 | |
| -1 | -150,117,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,117,469.
Example:
1 x 150,117,469 = 150,117,469
and
-1 x -150,117,469 = 150,117,469
Notice both answers equal 150,117,469
With that explanation out of the way, let's continue. Next, we take the number 150,117,469 and divide it by 2:
150,117,469 ÷ 2 = 75,058,734.5
If the quotient is a whole number, then 2 and 75,058,734.5 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 | 150,117,469 | |
| -1 | -150,117,469 |
Now, we try dividing 150,117,469 by 3:
150,117,469 ÷ 3 = 50,039,156.3333
If the quotient is a whole number, then 3 and 50,039,156.3333 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 | 150,117,469 | |
| -1 | -150,117,469 |
Let's try dividing by 4:
150,117,469 ÷ 4 = 37,529,367.25
If the quotient is a whole number, then 4 and 37,529,367.25 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 | 150,117,469 | |
| -1 | 150,117,469 |
If you did it right, you will end up with this table:
| 1 | 31 | 107 | 167 | 271 | 3,317 | 5,177 | 8,401 | 17,869 | 28,997 | 45,257 | 553,939 | 898,907 | 1,402,967 | 4,842,499 | 150,117,469 |
| -1 | -31 | -107 | -167 | -271 | -3,317 | -5,177 | -8,401 | -17,869 | -28,997 | -45,257 | -553,939 | -898,907 | -1,402,967 | -4,842,499 | -150,117,469 |
