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 62,606,887, 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 | 62,606,887 | |
| -1 | -62,606,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,606,887.
Example:
1 x 62,606,887 = 62,606,887
and
-1 x -62,606,887 = 62,606,887
Notice both answers equal 62,606,887
With that explanation out of the way, let's continue. Next, we take the number 62,606,887 and divide it by 2:
62,606,887 ÷ 2 = 31,303,443.5
If the quotient is a whole number, then 2 and 31,303,443.5 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 | 62,606,887 | |
| -1 | -62,606,887 |
Now, we try dividing 62,606,887 by 3:
62,606,887 ÷ 3 = 20,868,962.3333
If the quotient is a whole number, then 3 and 20,868,962.3333 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 | 62,606,887 | |
| -1 | -62,606,887 |
Let's try dividing by 4:
62,606,887 ÷ 4 = 15,651,721.75
If the quotient is a whole number, then 4 and 15,651,721.75 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 | 62,606,887 | |
| -1 | 62,606,887 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 263 | 1,097 | 1,841 | 7,679 | 8,153 | 34,007 | 57,071 | 238,049 | 288,511 | 2,019,577 | 8,943,841 | 62,606,887 |
| -1 | -7 | -31 | -217 | -263 | -1,097 | -1,841 | -7,679 | -8,153 | -34,007 | -57,071 | -238,049 | -288,511 | -2,019,577 | -8,943,841 | -62,606,887 |
