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 144,733,015, 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 | 144,733,015 | |
| -1 | -144,733,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,733,015.
Example:
1 x 144,733,015 = 144,733,015
and
-1 x -144,733,015 = 144,733,015
Notice both answers equal 144,733,015
With that explanation out of the way, let's continue. Next, we take the number 144,733,015 and divide it by 2:
144,733,015 ÷ 2 = 72,366,507.5
If the quotient is a whole number, then 2 and 72,366,507.5 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 | 144,733,015 | |
| -1 | -144,733,015 |
Now, we try dividing 144,733,015 by 3:
144,733,015 ÷ 3 = 48,244,338.3333
If the quotient is a whole number, then 3 and 48,244,338.3333 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 | 144,733,015 | |
| -1 | -144,733,015 |
Let's try dividing by 4:
144,733,015 ÷ 4 = 36,183,253.75
If the quotient is a whole number, then 4 and 36,183,253.75 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 | 144,733,015 | |
| -1 | 144,733,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 107 | 245 | 535 | 749 | 3,745 | 5,243 | 5,521 | 26,215 | 27,605 | 38,647 | 193,235 | 270,529 | 590,747 | 1,352,645 | 2,953,735 | 4,135,229 | 20,676,145 | 28,946,603 | 144,733,015 |
| -1 | -5 | -7 | -35 | -49 | -107 | -245 | -535 | -749 | -3,745 | -5,243 | -5,521 | -26,215 | -27,605 | -38,647 | -193,235 | -270,529 | -590,747 | -1,352,645 | -2,953,735 | -4,135,229 | -20,676,145 | -28,946,603 | -144,733,015 |
