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 2,674,555, 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 | 2,674,555 | |
| -1 | -2,674,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,674,555.
Example:
1 x 2,674,555 = 2,674,555
and
-1 x -2,674,555 = 2,674,555
Notice both answers equal 2,674,555
With that explanation out of the way, let's continue. Next, we take the number 2,674,555 and divide it by 2:
2,674,555 ÷ 2 = 1,337,277.5
If the quotient is a whole number, then 2 and 1,337,277.5 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 | 2,674,555 | |
| -1 | -2,674,555 |
Now, we try dividing 2,674,555 by 3:
2,674,555 ÷ 3 = 891,518.3333
If the quotient is a whole number, then 3 and 891,518.3333 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 | 2,674,555 | |
| -1 | -2,674,555 |
Let's try dividing by 4:
2,674,555 ÷ 4 = 668,638.75
If the quotient is a whole number, then 4 and 668,638.75 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 | 2,674,555 | |
| -1 | 2,674,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 1,789 | 8,945 | 23,257 | 41,147 | 116,285 | 205,735 | 534,911 | 2,674,555 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -1,789 | -8,945 | -23,257 | -41,147 | -116,285 | -205,735 | -534,911 | -2,674,555 |
