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 144,861,115, 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 | 144,861,115 | |
| -1 | -144,861,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,861,115.
Example:
1 x 144,861,115 = 144,861,115
and
-1 x -144,861,115 = 144,861,115
Notice both answers equal 144,861,115
With that explanation out of the way, let's continue. Next, we take the number 144,861,115 and divide it by 2:
144,861,115 ÷ 2 = 72,430,557.5
If the quotient is a whole number, then 2 and 72,430,557.5 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 | 144,861,115 | |
| -1 | -144,861,115 |
Now, we try dividing 144,861,115 by 3:
144,861,115 ÷ 3 = 48,287,038.3333
If the quotient is a whole number, then 3 and 48,287,038.3333 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 | 144,861,115 | |
| -1 | -144,861,115 |
Let's try dividing by 4:
144,861,115 ÷ 4 = 36,215,278.75
If the quotient is a whole number, then 4 and 36,215,278.75 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 | 144,861,115 | |
| -1 | 144,861,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 52,391 | 261,955 | 366,737 | 1,833,685 | 4,138,889 | 20,694,445 | 28,972,223 | 144,861,115 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -52,391 | -261,955 | -366,737 | -1,833,685 | -4,138,889 | -20,694,445 | -28,972,223 | -144,861,115 |
