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 144,362,315, 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 | 144,362,315 | |
| -1 | -144,362,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,362,315.
Example:
1 x 144,362,315 = 144,362,315
and
-1 x -144,362,315 = 144,362,315
Notice both answers equal 144,362,315
With that explanation out of the way, let's continue. Next, we take the number 144,362,315 and divide it by 2:
144,362,315 ÷ 2 = 72,181,157.5
If the quotient is a whole number, then 2 and 72,181,157.5 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 | 144,362,315 | |
| -1 | -144,362,315 |
Now, we try dividing 144,362,315 by 3:
144,362,315 ÷ 3 = 48,120,771.6667
If the quotient is a whole number, then 3 and 48,120,771.6667 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 | 144,362,315 | |
| -1 | -144,362,315 |
Let's try dividing by 4:
144,362,315 ÷ 4 = 36,090,578.75
If the quotient is a whole number, then 4 and 36,090,578.75 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 | 144,362,315 | |
| -1 | 144,362,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 167 | 415 | 835 | 2,083 | 10,415 | 13,861 | 69,305 | 172,889 | 347,861 | 864,445 | 1,739,305 | 28,872,463 | 144,362,315 |
| -1 | -5 | -83 | -167 | -415 | -835 | -2,083 | -10,415 | -13,861 | -69,305 | -172,889 | -347,861 | -864,445 | -1,739,305 | -28,872,463 | -144,362,315 |
