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 144,140,843, 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 | 144,140,843 | |
| -1 | -144,140,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,140,843.
Example:
1 x 144,140,843 = 144,140,843
and
-1 x -144,140,843 = 144,140,843
Notice both answers equal 144,140,843
With that explanation out of the way, let's continue. Next, we take the number 144,140,843 and divide it by 2:
144,140,843 ÷ 2 = 72,070,421.5
If the quotient is a whole number, then 2 and 72,070,421.5 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 | 144,140,843 | |
| -1 | -144,140,843 |
Now, we try dividing 144,140,843 by 3:
144,140,843 ÷ 3 = 48,046,947.6667
If the quotient is a whole number, then 3 and 48,046,947.6667 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 | 144,140,843 | |
| -1 | -144,140,843 |
Let's try dividing by 4:
144,140,843 ÷ 4 = 36,035,210.75
If the quotient is a whole number, then 4 and 36,035,210.75 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 | 144,140,843 | |
| -1 | 144,140,843 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 353 | 2,471 | 3,883 | 5,303 | 27,181 | 37,121 | 58,333 | 408,331 | 1,871,959 | 13,103,713 | 20,591,549 | 144,140,843 |
| -1 | -7 | -11 | -77 | -353 | -2,471 | -3,883 | -5,303 | -27,181 | -37,121 | -58,333 | -408,331 | -1,871,959 | -13,103,713 | -20,591,549 | -144,140,843 |
