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 313,702,177, 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 | 313,702,177 | |
-1 | -313,702,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,702,177.
Example:
1 x 313,702,177 = 313,702,177
and
-1 x -313,702,177 = 313,702,177
Notice both answers equal 313,702,177
With that explanation out of the way, let's continue. Next, we take the number 313,702,177 and divide it by 2:
313,702,177 ÷ 2 = 156,851,088.5
If the quotient is a whole number, then 2 and 156,851,088.5 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 | 313,702,177 | |
-1 | -313,702,177 |
Now, we try dividing 313,702,177 by 3:
313,702,177 ÷ 3 = 104,567,392.3333
If the quotient is a whole number, then 3 and 104,567,392.3333 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 | 313,702,177 | |
-1 | -313,702,177 |
Let's try dividing by 4:
313,702,177 ÷ 4 = 78,425,544.25
If the quotient is a whole number, then 4 and 78,425,544.25 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 | 313,702,177 | |
-1 | 313,702,177 |
If you did it right, you will end up with this table:
1 | 53 | 5,918,909 | 313,702,177 |
-1 | -53 | -5,918,909 | -313,702,177 |
