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 540,610,145, 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 | 540,610,145 | |
| -1 | -540,610,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,610,145.
Example:
1 x 540,610,145 = 540,610,145
and
-1 x -540,610,145 = 540,610,145
Notice both answers equal 540,610,145
With that explanation out of the way, let's continue. Next, we take the number 540,610,145 and divide it by 2:
540,610,145 ÷ 2 = 270,305,072.5
If the quotient is a whole number, then 2 and 270,305,072.5 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 | 540,610,145 | |
| -1 | -540,610,145 |
Now, we try dividing 540,610,145 by 3:
540,610,145 ÷ 3 = 180,203,381.6667
If the quotient is a whole number, then 3 and 180,203,381.6667 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 | 540,610,145 | |
| -1 | -540,610,145 |
Let's try dividing by 4:
540,610,145 ÷ 4 = 135,152,536.25
If the quotient is a whole number, then 4 and 135,152,536.25 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 | 540,610,145 | |
| -1 | 540,610,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 131 | 185 | 655 | 4,847 | 22,307 | 24,235 | 111,535 | 825,359 | 2,922,217 | 4,126,795 | 14,611,085 | 108,122,029 | 540,610,145 |
| -1 | -5 | -37 | -131 | -185 | -655 | -4,847 | -22,307 | -24,235 | -111,535 | -825,359 | -2,922,217 | -4,126,795 | -14,611,085 | -108,122,029 | -540,610,145 |
