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 141,840,095, 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 | 141,840,095 | |
| -1 | -141,840,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,840,095.
Example:
1 x 141,840,095 = 141,840,095
and
-1 x -141,840,095 = 141,840,095
Notice both answers equal 141,840,095
With that explanation out of the way, let's continue. Next, we take the number 141,840,095 and divide it by 2:
141,840,095 ÷ 2 = 70,920,047.5
If the quotient is a whole number, then 2 and 70,920,047.5 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 | 141,840,095 | |
| -1 | -141,840,095 |
Now, we try dividing 141,840,095 by 3:
141,840,095 ÷ 3 = 47,280,031.6667
If the quotient is a whole number, then 3 and 47,280,031.6667 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 | 141,840,095 | |
| -1 | -141,840,095 |
Let's try dividing by 4:
141,840,095 ÷ 4 = 35,460,023.75
If the quotient is a whole number, then 4 and 35,460,023.75 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 | 141,840,095 | |
| -1 | 141,840,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 73 | 85 | 365 | 1,241 | 6,205 | 22,859 | 114,295 | 388,603 | 1,668,707 | 1,943,015 | 8,343,535 | 28,368,019 | 141,840,095 |
| -1 | -5 | -17 | -73 | -85 | -365 | -1,241 | -6,205 | -22,859 | -114,295 | -388,603 | -1,668,707 | -1,943,015 | -8,343,535 | -28,368,019 | -141,840,095 |
