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 270,060,685, 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 | 270,060,685 | |
| -1 | -270,060,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 270,060,685.
Example:
1 x 270,060,685 = 270,060,685
and
-1 x -270,060,685 = 270,060,685
Notice both answers equal 270,060,685
With that explanation out of the way, let's continue. Next, we take the number 270,060,685 and divide it by 2:
270,060,685 ÷ 2 = 135,030,342.5
If the quotient is a whole number, then 2 and 135,030,342.5 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 | 270,060,685 | |
| -1 | -270,060,685 |
Now, we try dividing 270,060,685 by 3:
270,060,685 ÷ 3 = 90,020,228.3333
If the quotient is a whole number, then 3 and 90,020,228.3333 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 | 270,060,685 | |
| -1 | -270,060,685 |
Let's try dividing by 4:
270,060,685 ÷ 4 = 67,515,171.25
If the quotient is a whole number, then 4 and 67,515,171.25 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 | 270,060,685 | |
| -1 | 270,060,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 1,091 | 1,597 | 5,455 | 7,985 | 33,821 | 49,507 | 169,105 | 247,535 | 1,742,327 | 8,711,635 | 54,012,137 | 270,060,685 |
| -1 | -5 | -31 | -155 | -1,091 | -1,597 | -5,455 | -7,985 | -33,821 | -49,507 | -169,105 | -247,535 | -1,742,327 | -8,711,635 | -54,012,137 | -270,060,685 |
