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 62,475,517, 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 | 62,475,517 | |
| -1 | -62,475,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,475,517.
Example:
1 x 62,475,517 = 62,475,517
and
-1 x -62,475,517 = 62,475,517
Notice both answers equal 62,475,517
With that explanation out of the way, let's continue. Next, we take the number 62,475,517 and divide it by 2:
62,475,517 ÷ 2 = 31,237,758.5
If the quotient is a whole number, then 2 and 31,237,758.5 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 | 62,475,517 | |
| -1 | -62,475,517 |
Now, we try dividing 62,475,517 by 3:
62,475,517 ÷ 3 = 20,825,172.3333
If the quotient is a whole number, then 3 and 20,825,172.3333 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 | 62,475,517 | |
| -1 | -62,475,517 |
Let's try dividing by 4:
62,475,517 ÷ 4 = 15,618,879.25
If the quotient is a whole number, then 4 and 15,618,879.25 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 | 62,475,517 | |
| -1 | 62,475,517 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 73 | 559 | 949 | 1,531 | 3,139 | 19,903 | 40,807 | 65,833 | 111,763 | 855,829 | 1,452,919 | 4,805,809 | 62,475,517 |
| -1 | -13 | -43 | -73 | -559 | -949 | -1,531 | -3,139 | -19,903 | -40,807 | -65,833 | -111,763 | -855,829 | -1,452,919 | -4,805,809 | -62,475,517 |
