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 62,785,607, 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 | 62,785,607 | |
| -1 | -62,785,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,785,607.
Example:
1 x 62,785,607 = 62,785,607
and
-1 x -62,785,607 = 62,785,607
Notice both answers equal 62,785,607
With that explanation out of the way, let's continue. Next, we take the number 62,785,607 and divide it by 2:
62,785,607 ÷ 2 = 31,392,803.5
If the quotient is a whole number, then 2 and 31,392,803.5 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 | 62,785,607 | |
| -1 | -62,785,607 |
Now, we try dividing 62,785,607 by 3:
62,785,607 ÷ 3 = 20,928,535.6667
If the quotient is a whole number, then 3 and 20,928,535.6667 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 | 62,785,607 | |
| -1 | -62,785,607 |
Let's try dividing by 4:
62,785,607 ÷ 4 = 15,696,401.75
If the quotient is a whole number, then 4 and 15,696,401.75 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 | 62,785,607 | |
| -1 | 62,785,607 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 103 | 391 | 1,559 | 1,751 | 2,369 | 26,503 | 35,857 | 40,273 | 160,577 | 609,569 | 2,729,809 | 3,693,271 | 62,785,607 |
| -1 | -17 | -23 | -103 | -391 | -1,559 | -1,751 | -2,369 | -26,503 | -35,857 | -40,273 | -160,577 | -609,569 | -2,729,809 | -3,693,271 | -62,785,607 |
