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 62,051,515, 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 | 62,051,515 | |
| -1 | -62,051,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,051,515.
Example:
1 x 62,051,515 = 62,051,515
and
-1 x -62,051,515 = 62,051,515
Notice both answers equal 62,051,515
With that explanation out of the way, let's continue. Next, we take the number 62,051,515 and divide it by 2:
62,051,515 ÷ 2 = 31,025,757.5
If the quotient is a whole number, then 2 and 31,025,757.5 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 | 62,051,515 | |
| -1 | -62,051,515 |
Now, we try dividing 62,051,515 by 3:
62,051,515 ÷ 3 = 20,683,838.3333
If the quotient is a whole number, then 3 and 20,683,838.3333 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 | 62,051,515 | |
| -1 | -62,051,515 |
Let's try dividing by 4:
62,051,515 ÷ 4 = 15,512,878.75
If the quotient is a whole number, then 4 and 15,512,878.75 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 | 62,051,515 | |
| -1 | 62,051,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 71 | 235 | 355 | 3,337 | 3,719 | 16,685 | 18,595 | 174,793 | 264,049 | 873,965 | 1,320,245 | 12,410,303 | 62,051,515 |
| -1 | -5 | -47 | -71 | -235 | -355 | -3,337 | -3,719 | -16,685 | -18,595 | -174,793 | -264,049 | -873,965 | -1,320,245 | -12,410,303 | -62,051,515 |
