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 54,535,663, 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 | 54,535,663 | |
| -1 | -54,535,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,535,663.
Example:
1 x 54,535,663 = 54,535,663
and
-1 x -54,535,663 = 54,535,663
Notice both answers equal 54,535,663
With that explanation out of the way, let's continue. Next, we take the number 54,535,663 and divide it by 2:
54,535,663 ÷ 2 = 27,267,831.5
If the quotient is a whole number, then 2 and 27,267,831.5 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 | 54,535,663 | |
| -1 | -54,535,663 |
Now, we try dividing 54,535,663 by 3:
54,535,663 ÷ 3 = 18,178,554.3333
If the quotient is a whole number, then 3 and 18,178,554.3333 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 | 54,535,663 | |
| -1 | -54,535,663 |
Let's try dividing by 4:
54,535,663 ÷ 4 = 13,633,915.75
If the quotient is a whole number, then 4 and 13,633,915.75 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 | 54,535,663 | |
| -1 | 54,535,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 229 | 1,603 | 2,617 | 2,977 | 18,319 | 20,839 | 34,021 | 238,147 | 599,293 | 4,195,051 | 7,790,809 | 54,535,663 |
| -1 | -7 | -13 | -91 | -229 | -1,603 | -2,617 | -2,977 | -18,319 | -20,839 | -34,021 | -238,147 | -599,293 | -4,195,051 | -7,790,809 | -54,535,663 |
