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 270,179,063, 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 | 270,179,063 | |
| -1 | -270,179,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 270,179,063.
Example:
1 x 270,179,063 = 270,179,063
and
-1 x -270,179,063 = 270,179,063
Notice both answers equal 270,179,063
With that explanation out of the way, let's continue. Next, we take the number 270,179,063 and divide it by 2:
270,179,063 ÷ 2 = 135,089,531.5
If the quotient is a whole number, then 2 and 135,089,531.5 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 | 270,179,063 | |
| -1 | -270,179,063 |
Now, we try dividing 270,179,063 by 3:
270,179,063 ÷ 3 = 90,059,687.6667
If the quotient is a whole number, then 3 and 90,059,687.6667 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 | 270,179,063 | |
| -1 | -270,179,063 |
Let's try dividing by 4:
270,179,063 ÷ 4 = 67,544,765.75
If the quotient is a whole number, then 4 and 67,544,765.75 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 | 270,179,063 | |
| -1 | 270,179,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 109 | 763 | 1,199 | 8,393 | 32,191 | 225,337 | 354,101 | 2,478,707 | 3,508,819 | 24,561,733 | 38,597,009 | 270,179,063 |
| -1 | -7 | -11 | -77 | -109 | -763 | -1,199 | -8,393 | -32,191 | -225,337 | -354,101 | -2,478,707 | -3,508,819 | -24,561,733 | -38,597,009 | -270,179,063 |
