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 142,422,413, 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 | 142,422,413 | |
| -1 | -142,422,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,422,413.
Example:
1 x 142,422,413 = 142,422,413
and
-1 x -142,422,413 = 142,422,413
Notice both answers equal 142,422,413
With that explanation out of the way, let's continue. Next, we take the number 142,422,413 and divide it by 2:
142,422,413 ÷ 2 = 71,211,206.5
If the quotient is a whole number, then 2 and 71,211,206.5 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 | 142,422,413 | |
| -1 | -142,422,413 |
Now, we try dividing 142,422,413 by 3:
142,422,413 ÷ 3 = 47,474,137.6667
If the quotient is a whole number, then 3 and 47,474,137.6667 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 | 142,422,413 | |
| -1 | -142,422,413 |
Let's try dividing by 4:
142,422,413 ÷ 4 = 35,605,603.25
If the quotient is a whole number, then 4 and 35,605,603.25 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 | 142,422,413 | |
| -1 | 142,422,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 1,091 | 1,097 | 7,637 | 7,679 | 18,547 | 18,649 | 129,829 | 130,543 | 1,196,827 | 8,377,789 | 20,346,059 | 142,422,413 |
| -1 | -7 | -17 | -119 | -1,091 | -1,097 | -7,637 | -7,679 | -18,547 | -18,649 | -129,829 | -130,543 | -1,196,827 | -8,377,789 | -20,346,059 | -142,422,413 |
