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 141,143,101, 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 | 141,143,101 | |
| -1 | -141,143,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,143,101.
Example:
1 x 141,143,101 = 141,143,101
and
-1 x -141,143,101 = 141,143,101
Notice both answers equal 141,143,101
With that explanation out of the way, let's continue. Next, we take the number 141,143,101 and divide it by 2:
141,143,101 ÷ 2 = 70,571,550.5
If the quotient is a whole number, then 2 and 70,571,550.5 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 | 141,143,101 | |
| -1 | -141,143,101 |
Now, we try dividing 141,143,101 by 3:
141,143,101 ÷ 3 = 47,047,700.3333
If the quotient is a whole number, then 3 and 47,047,700.3333 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 | 141,143,101 | |
| -1 | -141,143,101 |
Let's try dividing by 4:
141,143,101 ÷ 4 = 35,285,775.25
If the quotient is a whole number, then 4 and 35,285,775.25 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 | 141,143,101 | |
| -1 | 141,143,101 |
If you did it right, you will end up with this table:
| 1 | 11 | 71 | 127 | 781 | 1,397 | 1,423 | 9,017 | 15,653 | 99,187 | 101,033 | 180,721 | 1,111,363 | 1,987,931 | 12,831,191 | 141,143,101 |
| -1 | -11 | -71 | -127 | -781 | -1,397 | -1,423 | -9,017 | -15,653 | -99,187 | -101,033 | -180,721 | -1,111,363 | -1,987,931 | -12,831,191 | -141,143,101 |
