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 62,567,015, 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 | 62,567,015 | |
| -1 | -62,567,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,567,015.
Example:
1 x 62,567,015 = 62,567,015
and
-1 x -62,567,015 = 62,567,015
Notice both answers equal 62,567,015
With that explanation out of the way, let's continue. Next, we take the number 62,567,015 and divide it by 2:
62,567,015 ÷ 2 = 31,283,507.5
If the quotient is a whole number, then 2 and 31,283,507.5 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 | 62,567,015 | |
| -1 | -62,567,015 |
Now, we try dividing 62,567,015 by 3:
62,567,015 ÷ 3 = 20,855,671.6667
If the quotient is a whole number, then 3 and 20,855,671.6667 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 | 62,567,015 | |
| -1 | -62,567,015 |
Let's try dividing by 4:
62,567,015 ÷ 4 = 15,641,753.75
If the quotient is a whole number, then 4 and 15,641,753.75 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 | 62,567,015 | |
| -1 | 62,567,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 77,723 | 388,615 | 544,061 | 1,787,629 | 2,720,305 | 8,938,145 | 12,513,403 | 62,567,015 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -77,723 | -388,615 | -544,061 | -1,787,629 | -2,720,305 | -8,938,145 | -12,513,403 | -62,567,015 |
