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 150,318,961, 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 | 150,318,961 | |
| -1 | -150,318,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,318,961.
Example:
1 x 150,318,961 = 150,318,961
and
-1 x -150,318,961 = 150,318,961
Notice both answers equal 150,318,961
With that explanation out of the way, let's continue. Next, we take the number 150,318,961 and divide it by 2:
150,318,961 ÷ 2 = 75,159,480.5
If the quotient is a whole number, then 2 and 75,159,480.5 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 | 150,318,961 | |
| -1 | -150,318,961 |
Now, we try dividing 150,318,961 by 3:
150,318,961 ÷ 3 = 50,106,320.3333
If the quotient is a whole number, then 3 and 50,106,320.3333 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 | 150,318,961 | |
| -1 | -150,318,961 |
Let's try dividing by 4:
150,318,961 ÷ 4 = 37,579,740.25
If the quotient is a whole number, then 4 and 37,579,740.25 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 | 150,318,961 | |
| -1 | 150,318,961 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 59 | 299 | 767 | 1,357 | 8,521 | 17,641 | 110,773 | 195,983 | 502,739 | 2,547,779 | 6,535,607 | 11,562,997 | 150,318,961 |
| -1 | -13 | -23 | -59 | -299 | -767 | -1,357 | -8,521 | -17,641 | -110,773 | -195,983 | -502,739 | -2,547,779 | -6,535,607 | -11,562,997 | -150,318,961 |
