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 63,555,245, 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 | 63,555,245 | |
| -1 | -63,555,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,555,245.
Example:
1 x 63,555,245 = 63,555,245
and
-1 x -63,555,245 = 63,555,245
Notice both answers equal 63,555,245
With that explanation out of the way, let's continue. Next, we take the number 63,555,245 and divide it by 2:
63,555,245 ÷ 2 = 31,777,622.5
If the quotient is a whole number, then 2 and 31,777,622.5 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 | 63,555,245 | |
| -1 | -63,555,245 |
Now, we try dividing 63,555,245 by 3:
63,555,245 ÷ 3 = 21,185,081.6667
If the quotient is a whole number, then 3 and 21,185,081.6667 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 | 63,555,245 | |
| -1 | -63,555,245 |
Let's try dividing by 4:
63,555,245 ÷ 4 = 15,888,811.25
If the quotient is a whole number, then 4 and 15,888,811.25 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 | 63,555,245 | |
| -1 | 63,555,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 127 | 635 | 1,651 | 7,699 | 8,255 | 38,495 | 100,087 | 500,435 | 977,773 | 4,888,865 | 12,711,049 | 63,555,245 |
| -1 | -5 | -13 | -65 | -127 | -635 | -1,651 | -7,699 | -8,255 | -38,495 | -100,087 | -500,435 | -977,773 | -4,888,865 | -12,711,049 | -63,555,245 |
