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 274,547,777, 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 | 274,547,777 | |
| -1 | -274,547,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 274,547,777.
Example:
1 x 274,547,777 = 274,547,777
and
-1 x -274,547,777 = 274,547,777
Notice both answers equal 274,547,777
With that explanation out of the way, let's continue. Next, we take the number 274,547,777 and divide it by 2:
274,547,777 ÷ 2 = 137,273,888.5
If the quotient is a whole number, then 2 and 137,273,888.5 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 | 274,547,777 | |
| -1 | -274,547,777 |
Now, we try dividing 274,547,777 by 3:
274,547,777 ÷ 3 = 91,515,925.6667
If the quotient is a whole number, then 3 and 91,515,925.6667 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 | 274,547,777 | |
| -1 | -274,547,777 |
Let's try dividing by 4:
274,547,777 ÷ 4 = 68,636,944.25
If the quotient is a whole number, then 4 and 68,636,944.25 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 | 274,547,777 | |
| -1 | 274,547,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 457 | 3,199 | 4,517 | 8,683 | 31,619 | 60,781 | 85,823 | 600,761 | 2,064,269 | 14,449,883 | 39,221,111 | 274,547,777 |
| -1 | -7 | -19 | -133 | -457 | -3,199 | -4,517 | -8,683 | -31,619 | -60,781 | -85,823 | -600,761 | -2,064,269 | -14,449,883 | -39,221,111 | -274,547,777 |
