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 62,163,515, 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 | 62,163,515 | |
| -1 | -62,163,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,163,515.
Example:
1 x 62,163,515 = 62,163,515
and
-1 x -62,163,515 = 62,163,515
Notice both answers equal 62,163,515
With that explanation out of the way, let's continue. Next, we take the number 62,163,515 and divide it by 2:
62,163,515 ÷ 2 = 31,081,757.5
If the quotient is a whole number, then 2 and 31,081,757.5 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 | 62,163,515 | |
| -1 | -62,163,515 |
Now, we try dividing 62,163,515 by 3:
62,163,515 ÷ 3 = 20,721,171.6667
If the quotient is a whole number, then 3 and 20,721,171.6667 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 | 62,163,515 | |
| -1 | -62,163,515 |
Let's try dividing by 4:
62,163,515 ÷ 4 = 15,540,878.75
If the quotient is a whole number, then 4 and 15,540,878.75 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 | 62,163,515 | |
| -1 | 62,163,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 73 | 185 | 365 | 2,701 | 4,603 | 13,505 | 23,015 | 170,311 | 336,019 | 851,555 | 1,680,095 | 12,432,703 | 62,163,515 |
| -1 | -5 | -37 | -73 | -185 | -365 | -2,701 | -4,603 | -13,505 | -23,015 | -170,311 | -336,019 | -851,555 | -1,680,095 | -12,432,703 | -62,163,515 |
