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 142,433,225, 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 | 142,433,225 | |
| -1 | -142,433,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,433,225.
Example:
1 x 142,433,225 = 142,433,225
and
-1 x -142,433,225 = 142,433,225
Notice both answers equal 142,433,225
With that explanation out of the way, let's continue. Next, we take the number 142,433,225 and divide it by 2:
142,433,225 ÷ 2 = 71,216,612.5
If the quotient is a whole number, then 2 and 71,216,612.5 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 | 142,433,225 | |
| -1 | -142,433,225 |
Now, we try dividing 142,433,225 by 3:
142,433,225 ÷ 3 = 47,477,741.6667
If the quotient is a whole number, then 3 and 47,477,741.6667 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 | 142,433,225 | |
| -1 | -142,433,225 |
Let's try dividing by 4:
142,433,225 ÷ 4 = 35,608,306.25
If the quotient is a whole number, then 4 and 35,608,306.25 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 | 142,433,225 | |
| -1 | 142,433,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 25 | 55 | 85 | 187 | 275 | 425 | 935 | 4,675 | 30,467 | 152,335 | 335,137 | 517,939 | 761,675 | 1,675,685 | 2,589,695 | 5,697,329 | 8,378,425 | 12,948,475 | 28,486,645 | 142,433,225 |
| -1 | -5 | -11 | -17 | -25 | -55 | -85 | -187 | -275 | -425 | -935 | -4,675 | -30,467 | -152,335 | -335,137 | -517,939 | -761,675 | -1,675,685 | -2,589,695 | -5,697,329 | -8,378,425 | -12,948,475 | -28,486,645 | -142,433,225 |
