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 63,502,355, 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 | 63,502,355 | |
| -1 | -63,502,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,502,355.
Example:
1 x 63,502,355 = 63,502,355
and
-1 x -63,502,355 = 63,502,355
Notice both answers equal 63,502,355
With that explanation out of the way, let's continue. Next, we take the number 63,502,355 and divide it by 2:
63,502,355 ÷ 2 = 31,751,177.5
If the quotient is a whole number, then 2 and 31,751,177.5 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 | 63,502,355 | |
| -1 | -63,502,355 |
Now, we try dividing 63,502,355 by 3:
63,502,355 ÷ 3 = 21,167,451.6667
If the quotient is a whole number, then 3 and 21,167,451.6667 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 | 63,502,355 | |
| -1 | -63,502,355 |
Let's try dividing by 4:
63,502,355 ÷ 4 = 15,875,588.75
If the quotient is a whole number, then 4 and 15,875,588.75 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 | 63,502,355 | |
| -1 | 63,502,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 163 | 815 | 1,141 | 5,705 | 11,131 | 55,655 | 77,917 | 389,585 | 1,814,353 | 9,071,765 | 12,700,471 | 63,502,355 |
| -1 | -5 | -7 | -35 | -163 | -815 | -1,141 | -5,705 | -11,131 | -55,655 | -77,917 | -389,585 | -1,814,353 | -9,071,765 | -12,700,471 | -63,502,355 |
