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 144,424,511, 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 | 144,424,511 | |
| -1 | -144,424,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,424,511.
Example:
1 x 144,424,511 = 144,424,511
and
-1 x -144,424,511 = 144,424,511
Notice both answers equal 144,424,511
With that explanation out of the way, let's continue. Next, we take the number 144,424,511 and divide it by 2:
144,424,511 ÷ 2 = 72,212,255.5
If the quotient is a whole number, then 2 and 72,212,255.5 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 | 144,424,511 | |
| -1 | -144,424,511 |
Now, we try dividing 144,424,511 by 3:
144,424,511 ÷ 3 = 48,141,503.6667
If the quotient is a whole number, then 3 and 48,141,503.6667 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 | 144,424,511 | |
| -1 | -144,424,511 |
Let's try dividing by 4:
144,424,511 ÷ 4 = 36,106,127.75
If the quotient is a whole number, then 4 and 36,106,127.75 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 | 144,424,511 | |
| -1 | 144,424,511 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 539 | 847 | 5,929 | 24,359 | 170,513 | 267,949 | 1,193,591 | 1,875,643 | 2,947,439 | 13,129,501 | 20,632,073 | 144,424,511 |
| -1 | -7 | -11 | -49 | -77 | -121 | -539 | -847 | -5,929 | -24,359 | -170,513 | -267,949 | -1,193,591 | -1,875,643 | -2,947,439 | -13,129,501 | -20,632,073 | -144,424,511 |
