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 70,330,655, 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 | 70,330,655 | |
| -1 | -70,330,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,330,655.
Example:
1 x 70,330,655 = 70,330,655
and
-1 x -70,330,655 = 70,330,655
Notice both answers equal 70,330,655
With that explanation out of the way, let's continue. Next, we take the number 70,330,655 and divide it by 2:
70,330,655 ÷ 2 = 35,165,327.5
If the quotient is a whole number, then 2 and 35,165,327.5 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 | 70,330,655 | |
| -1 | -70,330,655 |
Now, we try dividing 70,330,655 by 3:
70,330,655 ÷ 3 = 23,443,551.6667
If the quotient is a whole number, then 3 and 23,443,551.6667 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 | 70,330,655 | |
| -1 | -70,330,655 |
Let's try dividing by 4:
70,330,655 ÷ 4 = 17,582,663.75
If the quotient is a whole number, then 4 and 17,582,663.75 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 | 70,330,655 | |
| -1 | 70,330,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 145 | 295 | 1,711 | 8,221 | 8,555 | 41,105 | 238,409 | 485,039 | 1,192,045 | 2,425,195 | 14,066,131 | 70,330,655 |
| -1 | -5 | -29 | -59 | -145 | -295 | -1,711 | -8,221 | -8,555 | -41,105 | -238,409 | -485,039 | -1,192,045 | -2,425,195 | -14,066,131 | -70,330,655 |
