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 149,903,383, 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 | 149,903,383 | |
| -1 | -149,903,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 149,903,383.
Example:
1 x 149,903,383 = 149,903,383
and
-1 x -149,903,383 = 149,903,383
Notice both answers equal 149,903,383
With that explanation out of the way, let's continue. Next, we take the number 149,903,383 and divide it by 2:
149,903,383 ÷ 2 = 74,951,691.5
If the quotient is a whole number, then 2 and 74,951,691.5 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 | 149,903,383 | |
| -1 | -149,903,383 |
Now, we try dividing 149,903,383 by 3:
149,903,383 ÷ 3 = 49,967,794.3333
If the quotient is a whole number, then 3 and 49,967,794.3333 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 | 149,903,383 | |
| -1 | -149,903,383 |
Let's try dividing by 4:
149,903,383 ÷ 4 = 37,475,845.75
If the quotient is a whole number, then 4 and 37,475,845.75 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 | 149,903,383 | |
| -1 | 149,903,383 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 73 | 217 | 511 | 2,263 | 9,463 | 15,841 | 66,241 | 293,353 | 690,799 | 2,053,471 | 4,835,593 | 21,414,769 | 149,903,383 |
| -1 | -7 | -31 | -73 | -217 | -511 | -2,263 | -9,463 | -15,841 | -66,241 | -293,353 | -690,799 | -2,053,471 | -4,835,593 | -21,414,769 | -149,903,383 |
