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 62,831,797, 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 | 62,831,797 | |
| -1 | -62,831,797 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,831,797.
Example:
1 x 62,831,797 = 62,831,797
and
-1 x -62,831,797 = 62,831,797
Notice both answers equal 62,831,797
With that explanation out of the way, let's continue. Next, we take the number 62,831,797 and divide it by 2:
62,831,797 ÷ 2 = 31,415,898.5
If the quotient is a whole number, then 2 and 31,415,898.5 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 | 62,831,797 | |
| -1 | -62,831,797 |
Now, we try dividing 62,831,797 by 3:
62,831,797 ÷ 3 = 20,943,932.3333
If the quotient is a whole number, then 3 and 20,943,932.3333 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 | 62,831,797 | |
| -1 | -62,831,797 |
Let's try dividing by 4:
62,831,797 ÷ 4 = 15,707,949.25
If the quotient is a whole number, then 4 and 15,707,949.25 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 | 62,831,797 | |
| -1 | 62,831,797 |
If you did it right, you will end up with this table:
| 1 | 7 | 101 | 181 | 491 | 707 | 1,267 | 3,437 | 18,281 | 49,591 | 88,871 | 127,967 | 347,137 | 622,097 | 8,975,971 | 62,831,797 |
| -1 | -7 | -101 | -181 | -491 | -707 | -1,267 | -3,437 | -18,281 | -49,591 | -88,871 | -127,967 | -347,137 | -622,097 | -8,975,971 | -62,831,797 |
