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 142,054,757, 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 | 142,054,757 | |
| -1 | -142,054,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,054,757.
Example:
1 x 142,054,757 = 142,054,757
and
-1 x -142,054,757 = 142,054,757
Notice both answers equal 142,054,757
With that explanation out of the way, let's continue. Next, we take the number 142,054,757 and divide it by 2:
142,054,757 ÷ 2 = 71,027,378.5
If the quotient is a whole number, then 2 and 71,027,378.5 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 | 142,054,757 | |
| -1 | -142,054,757 |
Now, we try dividing 142,054,757 by 3:
142,054,757 ÷ 3 = 47,351,585.6667
If the quotient is a whole number, then 3 and 47,351,585.6667 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 | 142,054,757 | |
| -1 | -142,054,757 |
Let's try dividing by 4:
142,054,757 ÷ 4 = 35,513,689.25
If the quotient is a whole number, then 4 and 35,513,689.25 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 | 142,054,757 | |
| -1 | 142,054,757 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 199 | 559 | 1,277 | 2,587 | 8,557 | 16,601 | 54,911 | 111,241 | 254,123 | 713,843 | 3,303,599 | 10,927,289 | 142,054,757 |
| -1 | -13 | -43 | -199 | -559 | -1,277 | -2,587 | -8,557 | -16,601 | -54,911 | -111,241 | -254,123 | -713,843 | -3,303,599 | -10,927,289 | -142,054,757 |
