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 142,001,119, 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 | 142,001,119 | |
| -1 | -142,001,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,001,119.
Example:
1 x 142,001,119 = 142,001,119
and
-1 x -142,001,119 = 142,001,119
Notice both answers equal 142,001,119
With that explanation out of the way, let's continue. Next, we take the number 142,001,119 and divide it by 2:
142,001,119 ÷ 2 = 71,000,559.5
If the quotient is a whole number, then 2 and 71,000,559.5 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 | 142,001,119 | |
| -1 | -142,001,119 |
Now, we try dividing 142,001,119 by 3:
142,001,119 ÷ 3 = 47,333,706.3333
If the quotient is a whole number, then 3 and 47,333,706.3333 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 | 142,001,119 | |
| -1 | -142,001,119 |
Let's try dividing by 4:
142,001,119 ÷ 4 = 35,500,279.75
If the quotient is a whole number, then 4 and 35,500,279.75 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 | 142,001,119 | |
| -1 | 142,001,119 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 409 | 1,571 | 5,317 | 6,953 | 20,423 | 26,707 | 90,389 | 347,191 | 642,539 | 8,353,007 | 10,923,163 | 142,001,119 |
| -1 | -13 | -17 | -221 | -409 | -1,571 | -5,317 | -6,953 | -20,423 | -26,707 | -90,389 | -347,191 | -642,539 | -8,353,007 | -10,923,163 | -142,001,119 |
