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 142,975, 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 | 142,975 | |
| -1 | -142,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,975.
Example:
1 x 142,975 = 142,975
and
-1 x -142,975 = 142,975
Notice both answers equal 142,975
With that explanation out of the way, let's continue. Next, we take the number 142,975 and divide it by 2:
142,975 ÷ 2 = 71,487.5
If the quotient is a whole number, then 2 and 71,487.5 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 | 142,975 | |
| -1 | -142,975 |
Now, we try dividing 142,975 by 3:
142,975 ÷ 3 = 47,658.3333
If the quotient is a whole number, then 3 and 47,658.3333 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 | 142,975 | |
| -1 | -142,975 |
Let's try dividing by 4:
142,975 ÷ 4 = 35,743.75
If the quotient is a whole number, then 4 and 35,743.75 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 | 142,975 | |
| -1 | 142,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 43 | 95 | 133 | 175 | 215 | 301 | 475 | 665 | 817 | 1,075 | 1,505 | 3,325 | 4,085 | 5,719 | 7,525 | 20,425 | 28,595 | 142,975 |
| -1 | -5 | -7 | -19 | -25 | -35 | -43 | -95 | -133 | -175 | -215 | -301 | -475 | -665 | -817 | -1,075 | -1,505 | -3,325 | -4,085 | -5,719 | -7,525 | -20,425 | -28,595 | -142,975 |
