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 62,665,415, 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 | 62,665,415 | |
| -1 | -62,665,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,665,415.
Example:
1 x 62,665,415 = 62,665,415
and
-1 x -62,665,415 = 62,665,415
Notice both answers equal 62,665,415
With that explanation out of the way, let's continue. Next, we take the number 62,665,415 and divide it by 2:
62,665,415 ÷ 2 = 31,332,707.5
If the quotient is a whole number, then 2 and 31,332,707.5 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 | 62,665,415 | |
| -1 | -62,665,415 |
Now, we try dividing 62,665,415 by 3:
62,665,415 ÷ 3 = 20,888,471.6667
If the quotient is a whole number, then 3 and 20,888,471.6667 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 | 62,665,415 | |
| -1 | -62,665,415 |
Let's try dividing by 4:
62,665,415 ÷ 4 = 15,666,353.75
If the quotient is a whole number, then 4 and 15,666,353.75 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 | 62,665,415 | |
| -1 | 62,665,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 83 | 155 | 415 | 2,573 | 4,871 | 12,865 | 24,355 | 151,001 | 404,293 | 755,005 | 2,021,465 | 12,533,083 | 62,665,415 |
| -1 | -5 | -31 | -83 | -155 | -415 | -2,573 | -4,871 | -12,865 | -24,355 | -151,001 | -404,293 | -755,005 | -2,021,465 | -12,533,083 | -62,665,415 |
