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 142,304,399, 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 | 142,304,399 | |
| -1 | -142,304,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,304,399.
Example:
1 x 142,304,399 = 142,304,399
and
-1 x -142,304,399 = 142,304,399
Notice both answers equal 142,304,399
With that explanation out of the way, let's continue. Next, we take the number 142,304,399 and divide it by 2:
142,304,399 ÷ 2 = 71,152,199.5
If the quotient is a whole number, then 2 and 71,152,199.5 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 | 142,304,399 | |
| -1 | -142,304,399 |
Now, we try dividing 142,304,399 by 3:
142,304,399 ÷ 3 = 47,434,799.6667
If the quotient is a whole number, then 3 and 47,434,799.6667 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 | 142,304,399 | |
| -1 | -142,304,399 |
Let's try dividing by 4:
142,304,399 ÷ 4 = 35,576,099.75
If the quotient is a whole number, then 4 and 35,576,099.75 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 | 142,304,399 | |
| -1 | 142,304,399 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 61 | 697 | 1,037 | 2,501 | 3,347 | 42,517 | 56,899 | 137,227 | 204,167 | 2,332,859 | 3,470,839 | 8,370,847 | 142,304,399 |
| -1 | -17 | -41 | -61 | -697 | -1,037 | -2,501 | -3,347 | -42,517 | -56,899 | -137,227 | -204,167 | -2,332,859 | -3,470,839 | -8,370,847 | -142,304,399 |
