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 144,641,105, 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 | 144,641,105 | |
| -1 | -144,641,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,641,105.
Example:
1 x 144,641,105 = 144,641,105
and
-1 x -144,641,105 = 144,641,105
Notice both answers equal 144,641,105
With that explanation out of the way, let's continue. Next, we take the number 144,641,105 and divide it by 2:
144,641,105 ÷ 2 = 72,320,552.5
If the quotient is a whole number, then 2 and 72,320,552.5 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 | 144,641,105 | |
| -1 | -144,641,105 |
Now, we try dividing 144,641,105 by 3:
144,641,105 ÷ 3 = 48,213,701.6667
If the quotient is a whole number, then 3 and 48,213,701.6667 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 | 144,641,105 | |
| -1 | -144,641,105 |
Let's try dividing by 4:
144,641,105 ÷ 4 = 36,160,276.25
If the quotient is a whole number, then 4 and 36,160,276.25 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 | 144,641,105 | |
| -1 | 144,641,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 56,611 | 283,055 | 396,277 | 1,981,385 | 4,132,603 | 20,663,015 | 28,928,221 | 144,641,105 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -56,611 | -283,055 | -396,277 | -1,981,385 | -4,132,603 | -20,663,015 | -28,928,221 | -144,641,105 |
