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 275,724,515, 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 | 275,724,515 | |
| -1 | -275,724,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 275,724,515.
Example:
1 x 275,724,515 = 275,724,515
and
-1 x -275,724,515 = 275,724,515
Notice both answers equal 275,724,515
With that explanation out of the way, let's continue. Next, we take the number 275,724,515 and divide it by 2:
275,724,515 ÷ 2 = 137,862,257.5
If the quotient is a whole number, then 2 and 137,862,257.5 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 | 275,724,515 | |
| -1 | -275,724,515 |
Now, we try dividing 275,724,515 by 3:
275,724,515 ÷ 3 = 91,908,171.6667
If the quotient is a whole number, then 3 and 91,908,171.6667 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 | 275,724,515 | |
| -1 | -275,724,515 |
Let's try dividing by 4:
275,724,515 ÷ 4 = 68,931,128.75
If the quotient is a whole number, then 4 and 68,931,128.75 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 | 275,724,515 | |
| -1 | 275,724,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 167 | 605 | 835 | 1,837 | 2,729 | 9,185 | 13,645 | 20,207 | 30,019 | 101,035 | 150,095 | 330,209 | 455,743 | 1,651,045 | 2,278,715 | 5,013,173 | 25,065,865 | 55,144,903 | 275,724,515 |
| -1 | -5 | -11 | -55 | -121 | -167 | -605 | -835 | -1,837 | -2,729 | -9,185 | -13,645 | -20,207 | -30,019 | -101,035 | -150,095 | -330,209 | -455,743 | -1,651,045 | -2,278,715 | -5,013,173 | -25,065,865 | -55,144,903 | -275,724,515 |
