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 304,151,137, 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 | 304,151,137 | |
| -1 | -304,151,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,151,137.
Example:
1 x 304,151,137 = 304,151,137
and
-1 x -304,151,137 = 304,151,137
Notice both answers equal 304,151,137
With that explanation out of the way, let's continue. Next, we take the number 304,151,137 and divide it by 2:
304,151,137 ÷ 2 = 152,075,568.5
If the quotient is a whole number, then 2 and 152,075,568.5 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 | 304,151,137 | |
| -1 | -304,151,137 |
Now, we try dividing 304,151,137 by 3:
304,151,137 ÷ 3 = 101,383,712.3333
If the quotient is a whole number, then 3 and 101,383,712.3333 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 | 304,151,137 | |
| -1 | -304,151,137 |
Let's try dividing by 4:
304,151,137 ÷ 4 = 76,037,784.25
If the quotient is a whole number, then 4 and 76,037,784.25 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 | 304,151,137 | |
| -1 | 304,151,137 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 283 | 937 | 1,147 | 8,773 | 10,471 | 29,047 | 34,669 | 265,171 | 324,601 | 1,074,739 | 8,220,301 | 9,811,327 | 304,151,137 |
| -1 | -31 | -37 | -283 | -937 | -1,147 | -8,773 | -10,471 | -29,047 | -34,669 | -265,171 | -324,601 | -1,074,739 | -8,220,301 | -9,811,327 | -304,151,137 |
