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 42,211,015, 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 | 42,211,015 | |
| -1 | -42,211,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,211,015.
Example:
1 x 42,211,015 = 42,211,015
and
-1 x -42,211,015 = 42,211,015
Notice both answers equal 42,211,015
With that explanation out of the way, let's continue. Next, we take the number 42,211,015 and divide it by 2:
42,211,015 ÷ 2 = 21,105,507.5
If the quotient is a whole number, then 2 and 21,105,507.5 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 | 42,211,015 | |
| -1 | -42,211,015 |
Now, we try dividing 42,211,015 by 3:
42,211,015 ÷ 3 = 14,070,338.3333
If the quotient is a whole number, then 3 and 14,070,338.3333 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 | 42,211,015 | |
| -1 | -42,211,015 |
Let's try dividing by 4:
42,211,015 ÷ 4 = 10,552,753.75
If the quotient is a whole number, then 4 and 10,552,753.75 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 | 42,211,015 | |
| -1 | 42,211,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 109,639 | 548,195 | 767,473 | 1,206,029 | 3,837,365 | 6,030,145 | 8,442,203 | 42,211,015 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -109,639 | -548,195 | -767,473 | -1,206,029 | -3,837,365 | -6,030,145 | -8,442,203 | -42,211,015 |
