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 2,277,145, 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 | 2,277,145 | |
| -1 | -2,277,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,277,145.
Example:
1 x 2,277,145 = 2,277,145
and
-1 x -2,277,145 = 2,277,145
Notice both answers equal 2,277,145
With that explanation out of the way, let's continue. Next, we take the number 2,277,145 and divide it by 2:
2,277,145 ÷ 2 = 1,138,572.5
If the quotient is a whole number, then 2 and 1,138,572.5 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 | 2,277,145 | |
| -1 | -2,277,145 |
Now, we try dividing 2,277,145 by 3:
2,277,145 ÷ 3 = 759,048.3333
If the quotient is a whole number, then 3 and 759,048.3333 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 | 2,277,145 | |
| -1 | -2,277,145 |
Let's try dividing by 4:
2,277,145 ÷ 4 = 569,286.25
If the quotient is a whole number, then 4 and 569,286.25 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 | 2,277,145 | |
| -1 | 2,277,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 661 | 689 | 3,305 | 3,445 | 8,593 | 35,033 | 42,965 | 175,165 | 455,429 | 2,277,145 |
| -1 | -5 | -13 | -53 | -65 | -265 | -661 | -689 | -3,305 | -3,445 | -8,593 | -35,033 | -42,965 | -175,165 | -455,429 | -2,277,145 |
