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 42,503,417, 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 | 42,503,417 | |
| -1 | -42,503,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,503,417.
Example:
1 x 42,503,417 = 42,503,417
and
-1 x -42,503,417 = 42,503,417
Notice both answers equal 42,503,417
With that explanation out of the way, let's continue. Next, we take the number 42,503,417 and divide it by 2:
42,503,417 ÷ 2 = 21,251,708.5
If the quotient is a whole number, then 2 and 21,251,708.5 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 | 42,503,417 | |
| -1 | -42,503,417 |
Now, we try dividing 42,503,417 by 3:
42,503,417 ÷ 3 = 14,167,805.6667
If the quotient is a whole number, then 3 and 14,167,805.6667 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 | 42,503,417 | |
| -1 | -42,503,417 |
Let's try dividing by 4:
42,503,417 ÷ 4 = 10,625,854.25
If the quotient is a whole number, then 4 and 10,625,854.25 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 | 42,503,417 | |
| -1 | 42,503,417 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 37 | 187 | 407 | 629 | 6,143 | 6,919 | 67,573 | 104,431 | 227,291 | 1,148,741 | 2,500,201 | 3,863,947 | 42,503,417 |
| -1 | -11 | -17 | -37 | -187 | -407 | -629 | -6,143 | -6,919 | -67,573 | -104,431 | -227,291 | -1,148,741 | -2,500,201 | -3,863,947 | -42,503,417 |
