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 53,417,273, 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 | 53,417,273 | |
| -1 | -53,417,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,417,273.
Example:
1 x 53,417,273 = 53,417,273
and
-1 x -53,417,273 = 53,417,273
Notice both answers equal 53,417,273
With that explanation out of the way, let's continue. Next, we take the number 53,417,273 and divide it by 2:
53,417,273 ÷ 2 = 26,708,636.5
If the quotient is a whole number, then 2 and 26,708,636.5 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 | 53,417,273 | |
| -1 | -53,417,273 |
Now, we try dividing 53,417,273 by 3:
53,417,273 ÷ 3 = 17,805,757.6667
If the quotient is a whole number, then 3 and 17,805,757.6667 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 | 53,417,273 | |
| -1 | -53,417,273 |
Let's try dividing by 4:
53,417,273 ÷ 4 = 13,354,318.25
If the quotient is a whole number, then 4 and 13,354,318.25 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 | 53,417,273 | |
| -1 | 53,417,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 427 | 793 | 5,551 | 9,623 | 67,361 | 125,099 | 587,003 | 875,693 | 4,109,021 | 7,631,039 | 53,417,273 |
| -1 | -7 | -13 | -61 | -91 | -427 | -793 | -5,551 | -9,623 | -67,361 | -125,099 | -587,003 | -875,693 | -4,109,021 | -7,631,039 | -53,417,273 |
