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 150,754,333, 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 | 150,754,333 | |
| -1 | -150,754,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,754,333.
Example:
1 x 150,754,333 = 150,754,333
and
-1 x -150,754,333 = 150,754,333
Notice both answers equal 150,754,333
With that explanation out of the way, let's continue. Next, we take the number 150,754,333 and divide it by 2:
150,754,333 ÷ 2 = 75,377,166.5
If the quotient is a whole number, then 2 and 75,377,166.5 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 | 150,754,333 | |
| -1 | -150,754,333 |
Now, we try dividing 150,754,333 by 3:
150,754,333 ÷ 3 = 50,251,444.3333
If the quotient is a whole number, then 3 and 50,251,444.3333 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 | 150,754,333 | |
| -1 | -150,754,333 |
Let's try dividing by 4:
150,754,333 ÷ 4 = 37,688,583.25
If the quotient is a whole number, then 4 and 37,688,583.25 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 | 150,754,333 | |
| -1 | 150,754,333 |
If you did it right, you will end up with this table:
| 1 | 31 | 47 | 107 | 967 | 1,457 | 3,317 | 5,029 | 29,977 | 45,449 | 103,469 | 155,899 | 1,408,919 | 3,207,539 | 4,863,043 | 150,754,333 |
| -1 | -31 | -47 | -107 | -967 | -1,457 | -3,317 | -5,029 | -29,977 | -45,449 | -103,469 | -155,899 | -1,408,919 | -3,207,539 | -4,863,043 | -150,754,333 |
