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 144,330,235, 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 | 144,330,235 | |
| -1 | -144,330,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,330,235.
Example:
1 x 144,330,235 = 144,330,235
and
-1 x -144,330,235 = 144,330,235
Notice both answers equal 144,330,235
With that explanation out of the way, let's continue. Next, we take the number 144,330,235 and divide it by 2:
144,330,235 ÷ 2 = 72,165,117.5
If the quotient is a whole number, then 2 and 72,165,117.5 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 | 144,330,235 | |
| -1 | -144,330,235 |
Now, we try dividing 144,330,235 by 3:
144,330,235 ÷ 3 = 48,110,078.3333
If the quotient is a whole number, then 3 and 48,110,078.3333 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 | 144,330,235 | |
| -1 | -144,330,235 |
Let's try dividing by 4:
144,330,235 ÷ 4 = 36,082,558.75
If the quotient is a whole number, then 4 and 36,082,558.75 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 | 144,330,235 | |
| -1 | 144,330,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 79 | 245 | 395 | 553 | 2,765 | 3,871 | 7,457 | 19,355 | 37,285 | 52,199 | 260,995 | 365,393 | 589,103 | 1,826,965 | 2,945,515 | 4,123,721 | 20,618,605 | 28,866,047 | 144,330,235 |
| -1 | -5 | -7 | -35 | -49 | -79 | -245 | -395 | -553 | -2,765 | -3,871 | -7,457 | -19,355 | -37,285 | -52,199 | -260,995 | -365,393 | -589,103 | -1,826,965 | -2,945,515 | -4,123,721 | -20,618,605 | -28,866,047 | -144,330,235 |
