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 42,515,035, 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 | 42,515,035 | |
| -1 | -42,515,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,515,035.
Example:
1 x 42,515,035 = 42,515,035
and
-1 x -42,515,035 = 42,515,035
Notice both answers equal 42,515,035
With that explanation out of the way, let's continue. Next, we take the number 42,515,035 and divide it by 2:
42,515,035 ÷ 2 = 21,257,517.5
If the quotient is a whole number, then 2 and 21,257,517.5 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 | 42,515,035 | |
| -1 | -42,515,035 |
Now, we try dividing 42,515,035 by 3:
42,515,035 ÷ 3 = 14,171,678.3333
If the quotient is a whole number, then 3 and 14,171,678.3333 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 | 42,515,035 | |
| -1 | -42,515,035 |
Let's try dividing by 4:
42,515,035 ÷ 4 = 10,628,758.75
If the quotient is a whole number, then 4 and 10,628,758.75 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 | 42,515,035 | |
| -1 | 42,515,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 79 | 185 | 395 | 2,909 | 2,923 | 14,545 | 14,615 | 107,633 | 229,811 | 538,165 | 1,149,055 | 8,503,007 | 42,515,035 |
| -1 | -5 | -37 | -79 | -185 | -395 | -2,909 | -2,923 | -14,545 | -14,615 | -107,633 | -229,811 | -538,165 | -1,149,055 | -8,503,007 | -42,515,035 |
