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 63,156,443, 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 | 63,156,443 | |
| -1 | -63,156,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,156,443.
Example:
1 x 63,156,443 = 63,156,443
and
-1 x -63,156,443 = 63,156,443
Notice both answers equal 63,156,443
With that explanation out of the way, let's continue. Next, we take the number 63,156,443 and divide it by 2:
63,156,443 ÷ 2 = 31,578,221.5
If the quotient is a whole number, then 2 and 31,578,221.5 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 | 63,156,443 | |
| -1 | -63,156,443 |
Now, we try dividing 63,156,443 by 3:
63,156,443 ÷ 3 = 21,052,147.6667
If the quotient is a whole number, then 3 and 21,052,147.6667 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 | 63,156,443 | |
| -1 | -63,156,443 |
Let's try dividing by 4:
63,156,443 ÷ 4 = 15,789,110.75
If the quotient is a whole number, then 4 and 15,789,110.75 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 | 63,156,443 | |
| -1 | 63,156,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 53 | 83 | 293 | 371 | 581 | 2,051 | 2,597 | 4,067 | 4,399 | 14,357 | 15,529 | 24,319 | 30,793 | 108,703 | 170,233 | 215,551 | 760,921 | 1,191,631 | 1,288,907 | 9,022,349 | 63,156,443 |
| -1 | -7 | -49 | -53 | -83 | -293 | -371 | -581 | -2,051 | -2,597 | -4,067 | -4,399 | -14,357 | -15,529 | -24,319 | -30,793 | -108,703 | -170,233 | -215,551 | -760,921 | -1,191,631 | -1,288,907 | -9,022,349 | -63,156,443 |
