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 63,624,205, 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 | 63,624,205 | |
| -1 | -63,624,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,624,205.
Example:
1 x 63,624,205 = 63,624,205
and
-1 x -63,624,205 = 63,624,205
Notice both answers equal 63,624,205
With that explanation out of the way, let's continue. Next, we take the number 63,624,205 and divide it by 2:
63,624,205 ÷ 2 = 31,812,102.5
If the quotient is a whole number, then 2 and 31,812,102.5 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 | 63,624,205 | |
| -1 | -63,624,205 |
Now, we try dividing 63,624,205 by 3:
63,624,205 ÷ 3 = 21,208,068.3333
If the quotient is a whole number, then 3 and 21,208,068.3333 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 | 63,624,205 | |
| -1 | -63,624,205 |
Let's try dividing by 4:
63,624,205 ÷ 4 = 15,906,051.25
If the quotient is a whole number, then 4 and 15,906,051.25 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 | 63,624,205 | |
| -1 | 63,624,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 257 | 335 | 739 | 1,285 | 3,695 | 17,219 | 49,513 | 86,095 | 189,923 | 247,565 | 949,615 | 12,724,841 | 63,624,205 |
| -1 | -5 | -67 | -257 | -335 | -739 | -1,285 | -3,695 | -17,219 | -49,513 | -86,095 | -189,923 | -247,565 | -949,615 | -12,724,841 | -63,624,205 |
