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 142,633,519, 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 | 142,633,519 | |
| -1 | -142,633,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,633,519.
Example:
1 x 142,633,519 = 142,633,519
and
-1 x -142,633,519 = 142,633,519
Notice both answers equal 142,633,519
With that explanation out of the way, let's continue. Next, we take the number 142,633,519 and divide it by 2:
142,633,519 ÷ 2 = 71,316,759.5
If the quotient is a whole number, then 2 and 71,316,759.5 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 | 142,633,519 | |
| -1 | -142,633,519 |
Now, we try dividing 142,633,519 by 3:
142,633,519 ÷ 3 = 47,544,506.3333
If the quotient is a whole number, then 3 and 47,544,506.3333 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 | 142,633,519 | |
| -1 | -142,633,519 |
Let's try dividing by 4:
142,633,519 ÷ 4 = 35,658,379.75
If the quotient is a whole number, then 4 and 35,658,379.75 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 | 142,633,519 | |
| -1 | 142,633,519 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 787 | 1,523 | 5,509 | 10,661 | 13,379 | 25,891 | 93,653 | 181,237 | 1,198,601 | 8,390,207 | 20,376,217 | 142,633,519 |
| -1 | -7 | -17 | -119 | -787 | -1,523 | -5,509 | -10,661 | -13,379 | -25,891 | -93,653 | -181,237 | -1,198,601 | -8,390,207 | -20,376,217 | -142,633,519 |
