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 53,554,505, 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 | 53,554,505 | |
| -1 | -53,554,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,554,505.
Example:
1 x 53,554,505 = 53,554,505
and
-1 x -53,554,505 = 53,554,505
Notice both answers equal 53,554,505
With that explanation out of the way, let's continue. Next, we take the number 53,554,505 and divide it by 2:
53,554,505 ÷ 2 = 26,777,252.5
If the quotient is a whole number, then 2 and 26,777,252.5 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 | 53,554,505 | |
| -1 | -53,554,505 |
Now, we try dividing 53,554,505 by 3:
53,554,505 ÷ 3 = 17,851,501.6667
If the quotient is a whole number, then 3 and 17,851,501.6667 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 | 53,554,505 | |
| -1 | -53,554,505 |
Let's try dividing by 4:
53,554,505 ÷ 4 = 13,388,626.25
If the quotient is a whole number, then 4 and 13,388,626.25 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 | 53,554,505 | |
| -1 | 53,554,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 7,055 | 7,591 | 37,955 | 129,047 | 630,053 | 645,235 | 3,150,265 | 10,710,901 | 53,554,505 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -7,055 | -7,591 | -37,955 | -129,047 | -630,053 | -645,235 | -3,150,265 | -10,710,901 | -53,554,505 |
