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 2,370,775, 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 | 2,370,775 | |
| -1 | -2,370,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,370,775.
Example:
1 x 2,370,775 = 2,370,775
and
-1 x -2,370,775 = 2,370,775
Notice both answers equal 2,370,775
With that explanation out of the way, let's continue. Next, we take the number 2,370,775 and divide it by 2:
2,370,775 ÷ 2 = 1,185,387.5
If the quotient is a whole number, then 2 and 1,185,387.5 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 | 2,370,775 | |
| -1 | -2,370,775 |
Now, we try dividing 2,370,775 by 3:
2,370,775 ÷ 3 = 790,258.3333
If the quotient is a whole number, then 3 and 790,258.3333 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 | 2,370,775 | |
| -1 | -2,370,775 |
Let's try dividing by 4:
2,370,775 ÷ 4 = 592,693.75
If the quotient is a whole number, then 4 and 592,693.75 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 | 2,370,775 | |
| -1 | 2,370,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 37 | 55 | 185 | 233 | 275 | 407 | 925 | 1,165 | 2,035 | 2,563 | 5,825 | 8,621 | 10,175 | 12,815 | 43,105 | 64,075 | 94,831 | 215,525 | 474,155 | 2,370,775 |
| -1 | -5 | -11 | -25 | -37 | -55 | -185 | -233 | -275 | -407 | -925 | -1,165 | -2,035 | -2,563 | -5,825 | -8,621 | -10,175 | -12,815 | -43,105 | -64,075 | -94,831 | -215,525 | -474,155 | -2,370,775 |
