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 63,814,535, 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 | 63,814,535 | |
| -1 | -63,814,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,814,535.
Example:
1 x 63,814,535 = 63,814,535
and
-1 x -63,814,535 = 63,814,535
Notice both answers equal 63,814,535
With that explanation out of the way, let's continue. Next, we take the number 63,814,535 and divide it by 2:
63,814,535 ÷ 2 = 31,907,267.5
If the quotient is a whole number, then 2 and 31,907,267.5 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 | 63,814,535 | |
| -1 | -63,814,535 |
Now, we try dividing 63,814,535 by 3:
63,814,535 ÷ 3 = 21,271,511.6667
If the quotient is a whole number, then 3 and 21,271,511.6667 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 | 63,814,535 | |
| -1 | -63,814,535 |
Let's try dividing by 4:
63,814,535 ÷ 4 = 15,953,633.75
If the quotient is a whole number, then 4 and 15,953,633.75 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 | 63,814,535 | |
| -1 | 63,814,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 643 | 863 | 3,215 | 4,315 | 14,789 | 19,849 | 73,945 | 99,245 | 554,909 | 2,774,545 | 12,762,907 | 63,814,535 |
| -1 | -5 | -23 | -115 | -643 | -863 | -3,215 | -4,315 | -14,789 | -19,849 | -73,945 | -99,245 | -554,909 | -2,774,545 | -12,762,907 | -63,814,535 |
