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 63,803,185, 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 | 63,803,185 | |
| -1 | -63,803,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,803,185.
Example:
1 x 63,803,185 = 63,803,185
and
-1 x -63,803,185 = 63,803,185
Notice both answers equal 63,803,185
With that explanation out of the way, let's continue. Next, we take the number 63,803,185 and divide it by 2:
63,803,185 ÷ 2 = 31,901,592.5
If the quotient is a whole number, then 2 and 31,901,592.5 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 | 63,803,185 | |
| -1 | -63,803,185 |
Now, we try dividing 63,803,185 by 3:
63,803,185 ÷ 3 = 21,267,728.3333
If the quotient is a whole number, then 3 and 21,267,728.3333 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 | 63,803,185 | |
| -1 | -63,803,185 |
Let's try dividing by 4:
63,803,185 ÷ 4 = 15,950,796.25
If the quotient is a whole number, then 4 and 15,950,796.25 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 | 63,803,185 | |
| -1 | 63,803,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 167 | 215 | 835 | 1,777 | 7,181 | 8,885 | 35,905 | 76,411 | 296,759 | 382,055 | 1,483,795 | 12,760,637 | 63,803,185 |
| -1 | -5 | -43 | -167 | -215 | -835 | -1,777 | -7,181 | -8,885 | -35,905 | -76,411 | -296,759 | -382,055 | -1,483,795 | -12,760,637 | -63,803,185 |
