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 63,231,853, 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 | 63,231,853 | |
| -1 | -63,231,853 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,231,853.
Example:
1 x 63,231,853 = 63,231,853
and
-1 x -63,231,853 = 63,231,853
Notice both answers equal 63,231,853
With that explanation out of the way, let's continue. Next, we take the number 63,231,853 and divide it by 2:
63,231,853 ÷ 2 = 31,615,926.5
If the quotient is a whole number, then 2 and 31,615,926.5 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 | 63,231,853 | |
| -1 | -63,231,853 |
Now, we try dividing 63,231,853 by 3:
63,231,853 ÷ 3 = 21,077,284.3333
If the quotient is a whole number, then 3 and 21,077,284.3333 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 | 63,231,853 | |
| -1 | -63,231,853 |
Let's try dividing by 4:
63,231,853 ÷ 4 = 15,807,963.25
If the quotient is a whole number, then 4 and 15,807,963.25 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 | 63,231,853 | |
| -1 | 63,231,853 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 67 | 851 | 1,109 | 1,541 | 2,479 | 25,507 | 41,033 | 57,017 | 74,303 | 943,759 | 1,708,969 | 2,749,211 | 63,231,853 |
| -1 | -23 | -37 | -67 | -851 | -1,109 | -1,541 | -2,479 | -25,507 | -41,033 | -57,017 | -74,303 | -943,759 | -1,708,969 | -2,749,211 | -63,231,853 |
