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 144,150,305, 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 | 144,150,305 | |
| -1 | -144,150,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,150,305.
Example:
1 x 144,150,305 = 144,150,305
and
-1 x -144,150,305 = 144,150,305
Notice both answers equal 144,150,305
With that explanation out of the way, let's continue. Next, we take the number 144,150,305 and divide it by 2:
144,150,305 ÷ 2 = 72,075,152.5
If the quotient is a whole number, then 2 and 72,075,152.5 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 | 144,150,305 | |
| -1 | -144,150,305 |
Now, we try dividing 144,150,305 by 3:
144,150,305 ÷ 3 = 48,050,101.6667
If the quotient is a whole number, then 3 and 48,050,101.6667 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 | 144,150,305 | |
| -1 | -144,150,305 |
Let's try dividing by 4:
144,150,305 ÷ 4 = 36,037,576.25
If the quotient is a whole number, then 4 and 36,037,576.25 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 | 144,150,305 | |
| -1 | 144,150,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,093 | 2,029 | 5,465 | 10,145 | 14,209 | 26,377 | 71,045 | 131,885 | 2,217,697 | 11,088,485 | 28,830,061 | 144,150,305 |
| -1 | -5 | -13 | -65 | -1,093 | -2,029 | -5,465 | -10,145 | -14,209 | -26,377 | -71,045 | -131,885 | -2,217,697 | -11,088,485 | -28,830,061 | -144,150,305 |
