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 2,760,415, 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 | 2,760,415 | |
| -1 | -2,760,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,760,415.
Example:
1 x 2,760,415 = 2,760,415
and
-1 x -2,760,415 = 2,760,415
Notice both answers equal 2,760,415
With that explanation out of the way, let's continue. Next, we take the number 2,760,415 and divide it by 2:
2,760,415 ÷ 2 = 1,380,207.5
If the quotient is a whole number, then 2 and 1,380,207.5 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 | 2,760,415 | |
| -1 | -2,760,415 |
Now, we try dividing 2,760,415 by 3:
2,760,415 ÷ 3 = 920,138.3333
If the quotient is a whole number, then 3 and 920,138.3333 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 | 2,760,415 | |
| -1 | -2,760,415 |
Let's try dividing by 4:
2,760,415 ÷ 4 = 690,103.75
If the quotient is a whole number, then 4 and 690,103.75 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 | 2,760,415 | |
| -1 | 2,760,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 593 | 665 | 931 | 2,965 | 4,151 | 4,655 | 11,267 | 20,755 | 29,057 | 56,335 | 78,869 | 145,285 | 394,345 | 552,083 | 2,760,415 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -593 | -665 | -931 | -2,965 | -4,151 | -4,655 | -11,267 | -20,755 | -29,057 | -56,335 | -78,869 | -145,285 | -394,345 | -552,083 | -2,760,415 |
