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 2,743,069, 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 | 2,743,069 | |
| -1 | -2,743,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,743,069.
Example:
1 x 2,743,069 = 2,743,069
and
-1 x -2,743,069 = 2,743,069
Notice both answers equal 2,743,069
With that explanation out of the way, let's continue. Next, we take the number 2,743,069 and divide it by 2:
2,743,069 ÷ 2 = 1,371,534.5
If the quotient is a whole number, then 2 and 1,371,534.5 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 | 2,743,069 | |
| -1 | -2,743,069 |
Now, we try dividing 2,743,069 by 3:
2,743,069 ÷ 3 = 914,356.3333
If the quotient is a whole number, then 3 and 914,356.3333 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 | 2,743,069 | |
| -1 | -2,743,069 |
Let's try dividing by 4:
2,743,069 ÷ 4 = 685,767.25
If the quotient is a whole number, then 4 and 685,767.25 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 | 2,743,069 | |
| -1 | 2,743,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 49 | 89 | 119 | 259 | 623 | 629 | 833 | 1,513 | 1,813 | 3,293 | 4,361 | 4,403 | 10,591 | 23,051 | 30,821 | 55,981 | 74,137 | 161,357 | 391,867 | 2,743,069 |
| -1 | -7 | -17 | -37 | -49 | -89 | -119 | -259 | -623 | -629 | -833 | -1,513 | -1,813 | -3,293 | -4,361 | -4,403 | -10,591 | -23,051 | -30,821 | -55,981 | -74,137 | -161,357 | -391,867 | -2,743,069 |
