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 141,411,151, 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 | 141,411,151 | |
| -1 | -141,411,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,411,151.
Example:
1 x 141,411,151 = 141,411,151
and
-1 x -141,411,151 = 141,411,151
Notice both answers equal 141,411,151
With that explanation out of the way, let's continue. Next, we take the number 141,411,151 and divide it by 2:
141,411,151 ÷ 2 = 70,705,575.5
If the quotient is a whole number, then 2 and 70,705,575.5 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 | 141,411,151 | |
| -1 | -141,411,151 |
Now, we try dividing 141,411,151 by 3:
141,411,151 ÷ 3 = 47,137,050.3333
If the quotient is a whole number, then 3 and 47,137,050.3333 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 | 141,411,151 | |
| -1 | -141,411,151 |
Let's try dividing by 4:
141,411,151 ÷ 4 = 35,352,787.75
If the quotient is a whole number, then 4 and 35,352,787.75 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 | 141,411,151 | |
| -1 | 141,411,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 119 | 259 | 629 | 4,403 | 32,117 | 224,819 | 545,989 | 1,188,329 | 3,821,923 | 8,318,303 | 20,201,593 | 141,411,151 |
| -1 | -7 | -17 | -37 | -119 | -259 | -629 | -4,403 | -32,117 | -224,819 | -545,989 | -1,188,329 | -3,821,923 | -8,318,303 | -20,201,593 | -141,411,151 |
