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 141,213,401, 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 | 141,213,401 | |
| -1 | -141,213,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,213,401.
Example:
1 x 141,213,401 = 141,213,401
and
-1 x -141,213,401 = 141,213,401
Notice both answers equal 141,213,401
With that explanation out of the way, let's continue. Next, we take the number 141,213,401 and divide it by 2:
141,213,401 ÷ 2 = 70,606,700.5
If the quotient is a whole number, then 2 and 70,606,700.5 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 | 141,213,401 | |
| -1 | -141,213,401 |
Now, we try dividing 141,213,401 by 3:
141,213,401 ÷ 3 = 47,071,133.6667
If the quotient is a whole number, then 3 and 47,071,133.6667 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 | 141,213,401 | |
| -1 | -141,213,401 |
Let's try dividing by 4:
141,213,401 ÷ 4 = 35,303,350.25
If the quotient is a whole number, then 4 and 35,303,350.25 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 | 141,213,401 | |
| -1 | 141,213,401 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 293 | 2,051 | 2,221 | 9,083 | 15,547 | 63,581 | 68,851 | 481,957 | 650,753 | 4,555,271 | 20,173,343 | 141,213,401 |
| -1 | -7 | -31 | -217 | -293 | -2,051 | -2,221 | -9,083 | -15,547 | -63,581 | -68,851 | -481,957 | -650,753 | -4,555,271 | -20,173,343 | -141,213,401 |
