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 62,521,019, 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 | 62,521,019 | |
| -1 | -62,521,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,521,019.
Example:
1 x 62,521,019 = 62,521,019
and
-1 x -62,521,019 = 62,521,019
Notice both answers equal 62,521,019
With that explanation out of the way, let's continue. Next, we take the number 62,521,019 and divide it by 2:
62,521,019 ÷ 2 = 31,260,509.5
If the quotient is a whole number, then 2 and 31,260,509.5 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 | 62,521,019 | |
| -1 | -62,521,019 |
Now, we try dividing 62,521,019 by 3:
62,521,019 ÷ 3 = 20,840,339.6667
If the quotient is a whole number, then 3 and 20,840,339.6667 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 | 62,521,019 | |
| -1 | -62,521,019 |
Let's try dividing by 4:
62,521,019 ÷ 4 = 15,630,254.75
If the quotient is a whole number, then 4 and 15,630,254.75 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 | 62,521,019 | |
| -1 | 62,521,019 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 367 | 911 | 4,037 | 6,239 | 10,021 | 15,487 | 68,629 | 170,357 | 334,337 | 3,677,707 | 5,683,729 | 62,521,019 |
| -1 | -11 | -17 | -187 | -367 | -911 | -4,037 | -6,239 | -10,021 | -15,487 | -68,629 | -170,357 | -334,337 | -3,677,707 | -5,683,729 | -62,521,019 |
