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 2,675,155, 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 | 2,675,155 | |
| -1 | -2,675,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,675,155.
Example:
1 x 2,675,155 = 2,675,155
and
-1 x -2,675,155 = 2,675,155
Notice both answers equal 2,675,155
With that explanation out of the way, let's continue. Next, we take the number 2,675,155 and divide it by 2:
2,675,155 ÷ 2 = 1,337,577.5
If the quotient is a whole number, then 2 and 1,337,577.5 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 | 2,675,155 | |
| -1 | -2,675,155 |
Now, we try dividing 2,675,155 by 3:
2,675,155 ÷ 3 = 891,718.3333
If the quotient is a whole number, then 3 and 891,718.3333 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 | 2,675,155 | |
| -1 | -2,675,155 |
Let's try dividing by 4:
2,675,155 ÷ 4 = 668,788.75
If the quotient is a whole number, then 4 and 668,788.75 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 | 2,675,155 | |
| -1 | 2,675,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 61 | 179 | 245 | 305 | 427 | 895 | 1,253 | 2,135 | 2,989 | 6,265 | 8,771 | 10,919 | 14,945 | 43,855 | 54,595 | 76,433 | 382,165 | 535,031 | 2,675,155 |
| -1 | -5 | -7 | -35 | -49 | -61 | -179 | -245 | -305 | -427 | -895 | -1,253 | -2,135 | -2,989 | -6,265 | -8,771 | -10,919 | -14,945 | -43,855 | -54,595 | -76,433 | -382,165 | -535,031 | -2,675,155 |
