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 670,311,271, 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 | 670,311,271 | |
| -1 | -670,311,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,311,271.
Example:
1 x 670,311,271 = 670,311,271
and
-1 x -670,311,271 = 670,311,271
Notice both answers equal 670,311,271
With that explanation out of the way, let's continue. Next, we take the number 670,311,271 and divide it by 2:
670,311,271 ÷ 2 = 335,155,635.5
If the quotient is a whole number, then 2 and 335,155,635.5 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 | 670,311,271 | |
| -1 | -670,311,271 |
Now, we try dividing 670,311,271 by 3:
670,311,271 ÷ 3 = 223,437,090.3333
If the quotient is a whole number, then 3 and 223,437,090.3333 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 | 670,311,271 | |
| -1 | -670,311,271 |
Let's try dividing by 4:
670,311,271 ÷ 4 = 167,577,817.75
If the quotient is a whole number, then 4 and 167,577,817.75 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 | 670,311,271 | |
| -1 | 670,311,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 797 | 877 | 959 | 5,579 | 6,139 | 109,189 | 120,149 | 698,969 | 764,323 | 841,043 | 4,892,783 | 95,758,753 | 670,311,271 |
| -1 | -7 | -137 | -797 | -877 | -959 | -5,579 | -6,139 | -109,189 | -120,149 | -698,969 | -764,323 | -841,043 | -4,892,783 | -95,758,753 | -670,311,271 |
