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 2,701,385, 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 | 2,701,385 | |
| -1 | -2,701,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,701,385.
Example:
1 x 2,701,385 = 2,701,385
and
-1 x -2,701,385 = 2,701,385
Notice both answers equal 2,701,385
With that explanation out of the way, let's continue. Next, we take the number 2,701,385 and divide it by 2:
2,701,385 ÷ 2 = 1,350,692.5
If the quotient is a whole number, then 2 and 1,350,692.5 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 | 2,701,385 | |
| -1 | -2,701,385 |
Now, we try dividing 2,701,385 by 3:
2,701,385 ÷ 3 = 900,461.6667
If the quotient is a whole number, then 3 and 900,461.6667 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 | 2,701,385 | |
| -1 | -2,701,385 |
Let's try dividing by 4:
2,701,385 ÷ 4 = 675,346.25
If the quotient is a whole number, then 4 and 675,346.25 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 | 2,701,385 | |
| -1 | 2,701,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 521 | 1,037 | 2,605 | 5,185 | 8,857 | 31,781 | 44,285 | 158,905 | 540,277 | 2,701,385 |
| -1 | -5 | -17 | -61 | -85 | -305 | -521 | -1,037 | -2,605 | -5,185 | -8,857 | -31,781 | -44,285 | -158,905 | -540,277 | -2,701,385 |
