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 63,163,451, 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 | 63,163,451 | |
| -1 | -63,163,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,163,451.
Example:
1 x 63,163,451 = 63,163,451
and
-1 x -63,163,451 = 63,163,451
Notice both answers equal 63,163,451
With that explanation out of the way, let's continue. Next, we take the number 63,163,451 and divide it by 2:
63,163,451 ÷ 2 = 31,581,725.5
If the quotient is a whole number, then 2 and 31,581,725.5 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 | 63,163,451 | |
| -1 | -63,163,451 |
Now, we try dividing 63,163,451 by 3:
63,163,451 ÷ 3 = 21,054,483.6667
If the quotient is a whole number, then 3 and 21,054,483.6667 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 | 63,163,451 | |
| -1 | -63,163,451 |
Let's try dividing by 4:
63,163,451 ÷ 4 = 15,790,862.75
If the quotient is a whole number, then 4 and 15,790,862.75 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 | 63,163,451 | |
| -1 | 63,163,451 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 151 | 299 | 1,399 | 1,963 | 3,473 | 18,187 | 32,177 | 45,149 | 211,249 | 418,301 | 2,746,237 | 4,858,727 | 63,163,451 |
| -1 | -13 | -23 | -151 | -299 | -1,399 | -1,963 | -3,473 | -18,187 | -32,177 | -45,149 | -211,249 | -418,301 | -2,746,237 | -4,858,727 | -63,163,451 |
