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 53,133,143, 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 | 53,133,143 | |
| -1 | -53,133,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,133,143.
Example:
1 x 53,133,143 = 53,133,143
and
-1 x -53,133,143 = 53,133,143
Notice both answers equal 53,133,143
With that explanation out of the way, let's continue. Next, we take the number 53,133,143 and divide it by 2:
53,133,143 ÷ 2 = 26,566,571.5
If the quotient is a whole number, then 2 and 26,566,571.5 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 | 53,133,143 | |
| -1 | -53,133,143 |
Now, we try dividing 53,133,143 by 3:
53,133,143 ÷ 3 = 17,711,047.6667
If the quotient is a whole number, then 3 and 17,711,047.6667 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 | 53,133,143 | |
| -1 | -53,133,143 |
Let's try dividing by 4:
53,133,143 ÷ 4 = 13,283,285.75
If the quotient is a whole number, then 4 and 13,283,285.75 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 | 53,133,143 | |
| -1 | 53,133,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 521 | 857 | 3,647 | 5,999 | 8,857 | 14,569 | 61,999 | 101,983 | 446,497 | 3,125,479 | 7,590,449 | 53,133,143 |
| -1 | -7 | -17 | -119 | -521 | -857 | -3,647 | -5,999 | -8,857 | -14,569 | -61,999 | -101,983 | -446,497 | -3,125,479 | -7,590,449 | -53,133,143 |
