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 63,554,315, 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 | 63,554,315 | |
| -1 | -63,554,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,554,315.
Example:
1 x 63,554,315 = 63,554,315
and
-1 x -63,554,315 = 63,554,315
Notice both answers equal 63,554,315
With that explanation out of the way, let's continue. Next, we take the number 63,554,315 and divide it by 2:
63,554,315 ÷ 2 = 31,777,157.5
If the quotient is a whole number, then 2 and 31,777,157.5 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 | 63,554,315 | |
| -1 | -63,554,315 |
Now, we try dividing 63,554,315 by 3:
63,554,315 ÷ 3 = 21,184,771.6667
If the quotient is a whole number, then 3 and 21,184,771.6667 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 | 63,554,315 | |
| -1 | -63,554,315 |
Let's try dividing by 4:
63,554,315 ÷ 4 = 15,888,578.75
If the quotient is a whole number, then 4 and 15,888,578.75 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 | 63,554,315 | |
| -1 | 63,554,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 79 | 395 | 869 | 4,345 | 14,627 | 73,135 | 160,897 | 804,485 | 1,155,533 | 5,777,665 | 12,710,863 | 63,554,315 |
| -1 | -5 | -11 | -55 | -79 | -395 | -869 | -4,345 | -14,627 | -73,135 | -160,897 | -804,485 | -1,155,533 | -5,777,665 | -12,710,863 | -63,554,315 |
