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 63,378,623, 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 | 63,378,623 | |
| -1 | -63,378,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,378,623.
Example:
1 x 63,378,623 = 63,378,623
and
-1 x -63,378,623 = 63,378,623
Notice both answers equal 63,378,623
With that explanation out of the way, let's continue. Next, we take the number 63,378,623 and divide it by 2:
63,378,623 ÷ 2 = 31,689,311.5
If the quotient is a whole number, then 2 and 31,689,311.5 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 | 63,378,623 | |
| -1 | -63,378,623 |
Now, we try dividing 63,378,623 by 3:
63,378,623 ÷ 3 = 21,126,207.6667
If the quotient is a whole number, then 3 and 21,126,207.6667 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 | 63,378,623 | |
| -1 | -63,378,623 |
Let's try dividing by 4:
63,378,623 ÷ 4 = 15,844,655.75
If the quotient is a whole number, then 4 and 15,844,655.75 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 | 63,378,623 | |
| -1 | 63,378,623 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 43,321 | 303,247 | 476,531 | 823,099 | 3,335,717 | 5,761,693 | 9,054,089 | 63,378,623 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -43,321 | -303,247 | -476,531 | -823,099 | -3,335,717 | -5,761,693 | -9,054,089 | -63,378,623 |
