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 53,161,393, 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 | 53,161,393 | |
-1 | -53,161,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,161,393.
Example:
1 x 53,161,393 = 53,161,393
and
-1 x -53,161,393 = 53,161,393
Notice both answers equal 53,161,393
With that explanation out of the way, let's continue. Next, we take the number 53,161,393 and divide it by 2:
53,161,393 ÷ 2 = 26,580,696.5
If the quotient is a whole number, then 2 and 26,580,696.5 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 | 53,161,393 | |
-1 | -53,161,393 |
Now, we try dividing 53,161,393 by 3:
53,161,393 ÷ 3 = 17,720,464.3333
If the quotient is a whole number, then 3 and 17,720,464.3333 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 | 53,161,393 | |
-1 | -53,161,393 |
Let's try dividing by 4:
53,161,393 ÷ 4 = 13,290,348.25
If the quotient is a whole number, then 4 and 13,290,348.25 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 | 53,161,393 | |
-1 | 53,161,393 |
If you did it right, you will end up with this table:
1 | 919 | 57,847 | 53,161,393 |
-1 | -919 | -57,847 | -53,161,393 |
