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 2,761,003, 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 | 2,761,003 | |
| -1 | -2,761,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,761,003.
Example:
1 x 2,761,003 = 2,761,003
and
-1 x -2,761,003 = 2,761,003
Notice both answers equal 2,761,003
With that explanation out of the way, let's continue. Next, we take the number 2,761,003 and divide it by 2:
2,761,003 ÷ 2 = 1,380,501.5
If the quotient is a whole number, then 2 and 1,380,501.5 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 | 2,761,003 | |
| -1 | -2,761,003 |
Now, we try dividing 2,761,003 by 3:
2,761,003 ÷ 3 = 920,334.3333
If the quotient is a whole number, then 3 and 920,334.3333 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 | 2,761,003 | |
| -1 | -2,761,003 |
Let's try dividing by 4:
2,761,003 ÷ 4 = 690,250.75
If the quotient is a whole number, then 4 and 690,250.75 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 | 2,761,003 | |
| -1 | 2,761,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 67 | 203 | 469 | 841 | 1,421 | 1,943 | 3,283 | 5,887 | 13,601 | 41,209 | 56,347 | 95,207 | 394,429 | 2,761,003 |
| -1 | -7 | -29 | -49 | -67 | -203 | -469 | -841 | -1,421 | -1,943 | -3,283 | -5,887 | -13,601 | -41,209 | -56,347 | -95,207 | -394,429 | -2,761,003 |
