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 63,215,773, 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 | 63,215,773 | |
| -1 | -63,215,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,215,773.
Example:
1 x 63,215,773 = 63,215,773
and
-1 x -63,215,773 = 63,215,773
Notice both answers equal 63,215,773
With that explanation out of the way, let's continue. Next, we take the number 63,215,773 and divide it by 2:
63,215,773 ÷ 2 = 31,607,886.5
If the quotient is a whole number, then 2 and 31,607,886.5 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 | 63,215,773 | |
| -1 | -63,215,773 |
Now, we try dividing 63,215,773 by 3:
63,215,773 ÷ 3 = 21,071,924.3333
If the quotient is a whole number, then 3 and 21,071,924.3333 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 | 63,215,773 | |
| -1 | -63,215,773 |
Let's try dividing by 4:
63,215,773 ÷ 4 = 15,803,943.25
If the quotient is a whole number, then 4 and 15,803,943.25 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 | 63,215,773 | |
| -1 | 63,215,773 |
If you did it right, you will end up with this table:
| 1 | 67 | 71 | 97 | 137 | 4,757 | 6,499 | 6,887 | 9,179 | 9,727 | 13,289 | 461,429 | 651,709 | 890,363 | 943,519 | 63,215,773 |
| -1 | -67 | -71 | -97 | -137 | -4,757 | -6,499 | -6,887 | -9,179 | -9,727 | -13,289 | -461,429 | -651,709 | -890,363 | -943,519 | -63,215,773 |
