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 63,042,623, 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 | 63,042,623 | |
| -1 | -63,042,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,042,623.
Example:
1 x 63,042,623 = 63,042,623
and
-1 x -63,042,623 = 63,042,623
Notice both answers equal 63,042,623
With that explanation out of the way, let's continue. Next, we take the number 63,042,623 and divide it by 2:
63,042,623 ÷ 2 = 31,521,311.5
If the quotient is a whole number, then 2 and 31,521,311.5 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 | 63,042,623 | |
| -1 | -63,042,623 |
Now, we try dividing 63,042,623 by 3:
63,042,623 ÷ 3 = 21,014,207.6667
If the quotient is a whole number, then 3 and 21,014,207.6667 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 | 63,042,623 | |
| -1 | -63,042,623 |
Let's try dividing by 4:
63,042,623 ÷ 4 = 15,760,655.75
If the quotient is a whole number, then 4 and 15,760,655.75 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 | 63,042,623 | |
| -1 | 63,042,623 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 353 | 823 | 2,471 | 5,761 | 10,943 | 25,513 | 76,601 | 178,591 | 290,519 | 2,033,633 | 9,006,089 | 63,042,623 |
| -1 | -7 | -31 | -217 | -353 | -823 | -2,471 | -5,761 | -10,943 | -25,513 | -76,601 | -178,591 | -290,519 | -2,033,633 | -9,006,089 | -63,042,623 |
