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 144,606,649, 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 | 144,606,649 | |
| -1 | -144,606,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,606,649.
Example:
1 x 144,606,649 = 144,606,649
and
-1 x -144,606,649 = 144,606,649
Notice both answers equal 144,606,649
With that explanation out of the way, let's continue. Next, we take the number 144,606,649 and divide it by 2:
144,606,649 ÷ 2 = 72,303,324.5
If the quotient is a whole number, then 2 and 72,303,324.5 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 | 144,606,649 | |
| -1 | -144,606,649 |
Now, we try dividing 144,606,649 by 3:
144,606,649 ÷ 3 = 48,202,216.3333
If the quotient is a whole number, then 3 and 48,202,216.3333 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 | 144,606,649 | |
| -1 | -144,606,649 |
Let's try dividing by 4:
144,606,649 ÷ 4 = 36,151,662.25
If the quotient is a whole number, then 4 and 36,151,662.25 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 | 144,606,649 | |
| -1 | 144,606,649 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 101 | 803 | 1,111 | 1,783 | 7,373 | 19,613 | 81,103 | 130,159 | 180,083 | 1,431,749 | 1,980,913 | 13,146,059 | 144,606,649 |
| -1 | -11 | -73 | -101 | -803 | -1,111 | -1,783 | -7,373 | -19,613 | -81,103 | -130,159 | -180,083 | -1,431,749 | -1,980,913 | -13,146,059 | -144,606,649 |
