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 670,773,415, 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 | 670,773,415 | |
| -1 | -670,773,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 670,773,415.
Example:
1 x 670,773,415 = 670,773,415
and
-1 x -670,773,415 = 670,773,415
Notice both answers equal 670,773,415
With that explanation out of the way, let's continue. Next, we take the number 670,773,415 and divide it by 2:
670,773,415 ÷ 2 = 335,386,707.5
If the quotient is a whole number, then 2 and 335,386,707.5 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 | 670,773,415 | |
| -1 | -670,773,415 |
Now, we try dividing 670,773,415 by 3:
670,773,415 ÷ 3 = 223,591,138.3333
If the quotient is a whole number, then 3 and 223,591,138.3333 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 | 670,773,415 | |
| -1 | -670,773,415 |
Let's try dividing by 4:
670,773,415 ÷ 4 = 167,693,353.75
If the quotient is a whole number, then 4 and 167,693,353.75 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 | 670,773,415 | |
| -1 | 670,773,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 149 | 745 | 1,937 | 9,685 | 69,259 | 346,295 | 900,367 | 4,501,835 | 10,319,591 | 51,597,955 | 134,154,683 | 670,773,415 |
| -1 | -5 | -13 | -65 | -149 | -745 | -1,937 | -9,685 | -69,259 | -346,295 | -900,367 | -4,501,835 | -10,319,591 | -51,597,955 | -134,154,683 | -670,773,415 |
