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 142,154,339, 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 | 142,154,339 | |
| -1 | -142,154,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,154,339.
Example:
1 x 142,154,339 = 142,154,339
and
-1 x -142,154,339 = 142,154,339
Notice both answers equal 142,154,339
With that explanation out of the way, let's continue. Next, we take the number 142,154,339 and divide it by 2:
142,154,339 ÷ 2 = 71,077,169.5
If the quotient is a whole number, then 2 and 71,077,169.5 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 | 142,154,339 | |
| -1 | -142,154,339 |
Now, we try dividing 142,154,339 by 3:
142,154,339 ÷ 3 = 47,384,779.6667
If the quotient is a whole number, then 3 and 47,384,779.6667 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 | 142,154,339 | |
| -1 | -142,154,339 |
Let's try dividing by 4:
142,154,339 ÷ 4 = 35,538,584.75
If the quotient is a whole number, then 4 and 35,538,584.75 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 | 142,154,339 | |
| -1 | 142,154,339 |
If you did it right, you will end up with this table:
| 1 | 41 | 61 | 113 | 503 | 2,501 | 4,633 | 6,893 | 20,623 | 30,683 | 56,839 | 282,613 | 1,258,003 | 2,330,399 | 3,467,179 | 142,154,339 |
| -1 | -41 | -61 | -113 | -503 | -2,501 | -4,633 | -6,893 | -20,623 | -30,683 | -56,839 | -282,613 | -1,258,003 | -2,330,399 | -3,467,179 | -142,154,339 |
