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 63,428,431, 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 | 63,428,431 | |
| -1 | -63,428,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,428,431.
Example:
1 x 63,428,431 = 63,428,431
and
-1 x -63,428,431 = 63,428,431
Notice both answers equal 63,428,431
With that explanation out of the way, let's continue. Next, we take the number 63,428,431 and divide it by 2:
63,428,431 ÷ 2 = 31,714,215.5
If the quotient is a whole number, then 2 and 31,714,215.5 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 | 63,428,431 | |
| -1 | -63,428,431 |
Now, we try dividing 63,428,431 by 3:
63,428,431 ÷ 3 = 21,142,810.3333
If the quotient is a whole number, then 3 and 21,142,810.3333 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 | 63,428,431 | |
| -1 | -63,428,431 |
Let's try dividing by 4:
63,428,431 ÷ 4 = 15,857,107.75
If the quotient is a whole number, then 4 and 15,857,107.75 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 | 63,428,431 | |
| -1 | 63,428,431 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 89 | 737 | 967 | 979 | 5,963 | 10,637 | 64,789 | 65,593 | 86,063 | 712,679 | 946,693 | 5,766,221 | 63,428,431 |
| -1 | -11 | -67 | -89 | -737 | -967 | -979 | -5,963 | -10,637 | -64,789 | -65,593 | -86,063 | -712,679 | -946,693 | -5,766,221 | -63,428,431 |
