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 274,506,845, 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 | 274,506,845 | |
| -1 | -274,506,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 274,506,845.
Example:
1 x 274,506,845 = 274,506,845
and
-1 x -274,506,845 = 274,506,845
Notice both answers equal 274,506,845
With that explanation out of the way, let's continue. Next, we take the number 274,506,845 and divide it by 2:
274,506,845 ÷ 2 = 137,253,422.5
If the quotient is a whole number, then 2 and 137,253,422.5 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 | 274,506,845 | |
| -1 | -274,506,845 |
Now, we try dividing 274,506,845 by 3:
274,506,845 ÷ 3 = 91,502,281.6667
If the quotient is a whole number, then 3 and 91,502,281.6667 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 | 274,506,845 | |
| -1 | -274,506,845 |
Let's try dividing by 4:
274,506,845 ÷ 4 = 68,626,711.25
If the quotient is a whole number, then 4 and 68,626,711.25 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 | 274,506,845 | |
| -1 | 274,506,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 433 | 515 | 1,231 | 2,165 | 6,155 | 44,599 | 126,793 | 222,995 | 533,023 | 633,965 | 2,665,115 | 54,901,369 | 274,506,845 |
| -1 | -5 | -103 | -433 | -515 | -1,231 | -2,165 | -6,155 | -44,599 | -126,793 | -222,995 | -533,023 | -633,965 | -2,665,115 | -54,901,369 | -274,506,845 |
