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 142,154,333, 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 | 142,154,333 | |
| -1 | -142,154,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,154,333.
Example:
1 x 142,154,333 = 142,154,333
and
-1 x -142,154,333 = 142,154,333
Notice both answers equal 142,154,333
With that explanation out of the way, let's continue. Next, we take the number 142,154,333 and divide it by 2:
142,154,333 ÷ 2 = 71,077,166.5
If the quotient is a whole number, then 2 and 71,077,166.5 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 | 142,154,333 | |
| -1 | -142,154,333 |
Now, we try dividing 142,154,333 by 3:
142,154,333 ÷ 3 = 47,384,777.6667
If the quotient is a whole number, then 3 and 47,384,777.6667 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 | 142,154,333 | |
| -1 | -142,154,333 |
Let's try dividing by 4:
142,154,333 ÷ 4 = 35,538,583.25
If the quotient is a whole number, then 4 and 35,538,583.25 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 | 142,154,333 | |
| -1 | 142,154,333 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 433 | 467 | 703 | 8,227 | 8,873 | 16,021 | 17,279 | 202,211 | 304,399 | 328,301 | 3,842,009 | 7,481,807 | 142,154,333 |
| -1 | -19 | -37 | -433 | -467 | -703 | -8,227 | -8,873 | -16,021 | -17,279 | -202,211 | -304,399 | -328,301 | -3,842,009 | -7,481,807 | -142,154,333 |
