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 150,306,929, 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 | 150,306,929 | |
| -1 | -150,306,929 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,306,929.
Example:
1 x 150,306,929 = 150,306,929
and
-1 x -150,306,929 = 150,306,929
Notice both answers equal 150,306,929
With that explanation out of the way, let's continue. Next, we take the number 150,306,929 and divide it by 2:
150,306,929 ÷ 2 = 75,153,464.5
If the quotient is a whole number, then 2 and 75,153,464.5 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 | 150,306,929 | |
| -1 | -150,306,929 |
Now, we try dividing 150,306,929 by 3:
150,306,929 ÷ 3 = 50,102,309.6667
If the quotient is a whole number, then 3 and 50,102,309.6667 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 | 150,306,929 | |
| -1 | -150,306,929 |
Let's try dividing by 4:
150,306,929 ÷ 4 = 37,576,732.25
If the quotient is a whole number, then 4 and 37,576,732.25 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 | 150,306,929 | |
| -1 | 150,306,929 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 71 | 1,273 | 1,349 | 1,663 | 4,757 | 31,597 | 90,383 | 111,421 | 118,073 | 2,116,999 | 2,243,387 | 7,910,891 | 150,306,929 |
| -1 | -19 | -67 | -71 | -1,273 | -1,349 | -1,663 | -4,757 | -31,597 | -90,383 | -111,421 | -118,073 | -2,116,999 | -2,243,387 | -7,910,891 | -150,306,929 |
