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 63,521,623, 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 | 63,521,623 | |
| -1 | -63,521,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,521,623.
Example:
1 x 63,521,623 = 63,521,623
and
-1 x -63,521,623 = 63,521,623
Notice both answers equal 63,521,623
With that explanation out of the way, let's continue. Next, we take the number 63,521,623 and divide it by 2:
63,521,623 ÷ 2 = 31,760,811.5
If the quotient is a whole number, then 2 and 31,760,811.5 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 | 63,521,623 | |
| -1 | -63,521,623 |
Now, we try dividing 63,521,623 by 3:
63,521,623 ÷ 3 = 21,173,874.3333
If the quotient is a whole number, then 3 and 21,173,874.3333 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 | 63,521,623 | |
| -1 | -63,521,623 |
Let's try dividing by 4:
63,521,623 ÷ 4 = 15,880,405.75
If the quotient is a whole number, then 4 and 15,880,405.75 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 | 63,521,623 | |
| -1 | 63,521,623 |
If you did it right, you will end up with this table:
| 1 | 11 | 151 | 167 | 229 | 1,661 | 1,837 | 2,519 | 25,217 | 34,579 | 38,243 | 277,387 | 380,369 | 420,673 | 5,774,693 | 63,521,623 |
| -1 | -11 | -151 | -167 | -229 | -1,661 | -1,837 | -2,519 | -25,217 | -34,579 | -38,243 | -277,387 | -380,369 | -420,673 | -5,774,693 | -63,521,623 |
