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 142,302,755, 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 | 142,302,755 | |
| -1 | -142,302,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,302,755.
Example:
1 x 142,302,755 = 142,302,755
and
-1 x -142,302,755 = 142,302,755
Notice both answers equal 142,302,755
With that explanation out of the way, let's continue. Next, we take the number 142,302,755 and divide it by 2:
142,302,755 ÷ 2 = 71,151,377.5
If the quotient is a whole number, then 2 and 71,151,377.5 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 | 142,302,755 | |
| -1 | -142,302,755 |
Now, we try dividing 142,302,755 by 3:
142,302,755 ÷ 3 = 47,434,251.6667
If the quotient is a whole number, then 3 and 47,434,251.6667 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 | 142,302,755 | |
| -1 | -142,302,755 |
Let's try dividing by 4:
142,302,755 ÷ 4 = 35,575,688.75
If the quotient is a whole number, then 4 and 35,575,688.75 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 | 142,302,755 | |
| -1 | 142,302,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 911 | 4,463 | 4,555 | 6,377 | 22,315 | 31,241 | 31,885 | 156,205 | 4,065,793 | 20,328,965 | 28,460,551 | 142,302,755 |
| -1 | -5 | -7 | -35 | -911 | -4,463 | -4,555 | -6,377 | -22,315 | -31,241 | -31,885 | -156,205 | -4,065,793 | -20,328,965 | -28,460,551 | -142,302,755 |
