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 142,333,015, 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 | 142,333,015 | |
| -1 | -142,333,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,333,015.
Example:
1 x 142,333,015 = 142,333,015
and
-1 x -142,333,015 = 142,333,015
Notice both answers equal 142,333,015
With that explanation out of the way, let's continue. Next, we take the number 142,333,015 and divide it by 2:
142,333,015 ÷ 2 = 71,166,507.5
If the quotient is a whole number, then 2 and 71,166,507.5 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 | 142,333,015 | |
| -1 | -142,333,015 |
Now, we try dividing 142,333,015 by 3:
142,333,015 ÷ 3 = 47,444,338.3333
If the quotient is a whole number, then 3 and 47,444,338.3333 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 | 142,333,015 | |
| -1 | -142,333,015 |
Let's try dividing by 4:
142,333,015 ÷ 4 = 35,583,253.75
If the quotient is a whole number, then 4 and 35,583,253.75 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 | 142,333,015 | |
| -1 | 142,333,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 89,237 | 446,185 | 981,607 | 2,587,873 | 4,908,035 | 12,939,365 | 28,466,603 | 142,333,015 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -89,237 | -446,185 | -981,607 | -2,587,873 | -4,908,035 | -12,939,365 | -28,466,603 | -142,333,015 |
