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 141,241,243, 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 | 141,241,243 | |
| -1 | -141,241,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,241,243.
Example:
1 x 141,241,243 = 141,241,243
and
-1 x -141,241,243 = 141,241,243
Notice both answers equal 141,241,243
With that explanation out of the way, let's continue. Next, we take the number 141,241,243 and divide it by 2:
141,241,243 ÷ 2 = 70,620,621.5
If the quotient is a whole number, then 2 and 70,620,621.5 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 | 141,241,243 | |
| -1 | -141,241,243 |
Now, we try dividing 141,241,243 by 3:
141,241,243 ÷ 3 = 47,080,414.3333
If the quotient is a whole number, then 3 and 47,080,414.3333 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 | 141,241,243 | |
| -1 | -141,241,243 |
Let's try dividing by 4:
141,241,243 ÷ 4 = 35,310,310.75
If the quotient is a whole number, then 4 and 35,310,310.75 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 | 141,241,243 | |
| -1 | 141,241,243 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 121 | 143 | 169 | 1,573 | 1,859 | 6,907 | 20,449 | 75,977 | 89,791 | 835,747 | 987,701 | 1,167,283 | 10,864,711 | 12,840,113 | 141,241,243 |
| -1 | -11 | -13 | -121 | -143 | -169 | -1,573 | -1,859 | -6,907 | -20,449 | -75,977 | -89,791 | -835,747 | -987,701 | -1,167,283 | -10,864,711 | -12,840,113 | -141,241,243 |
