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 144,424,205, 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 | 144,424,205 | |
| -1 | -144,424,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,424,205.
Example:
1 x 144,424,205 = 144,424,205
and
-1 x -144,424,205 = 144,424,205
Notice both answers equal 144,424,205
With that explanation out of the way, let's continue. Next, we take the number 144,424,205 and divide it by 2:
144,424,205 ÷ 2 = 72,212,102.5
If the quotient is a whole number, then 2 and 72,212,102.5 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 | 144,424,205 | |
| -1 | -144,424,205 |
Now, we try dividing 144,424,205 by 3:
144,424,205 ÷ 3 = 48,141,401.6667
If the quotient is a whole number, then 3 and 48,141,401.6667 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 | 144,424,205 | |
| -1 | -144,424,205 |
Let's try dividing by 4:
144,424,205 ÷ 4 = 36,106,051.25
If the quotient is a whole number, then 4 and 36,106,051.25 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 | 144,424,205 | |
| -1 | 144,424,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,537 | 7,685 | 18,793 | 93,965 | 544,997 | 996,029 | 2,724,985 | 4,980,145 | 28,884,841 | 144,424,205 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,537 | -7,685 | -18,793 | -93,965 | -544,997 | -996,029 | -2,724,985 | -4,980,145 | -28,884,841 | -144,424,205 |
