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 2,224,675, 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 | 2,224,675 | |
| -1 | -2,224,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,224,675.
Example:
1 x 2,224,675 = 2,224,675
and
-1 x -2,224,675 = 2,224,675
Notice both answers equal 2,224,675
With that explanation out of the way, let's continue. Next, we take the number 2,224,675 and divide it by 2:
2,224,675 ÷ 2 = 1,112,337.5
If the quotient is a whole number, then 2 and 1,112,337.5 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 | 2,224,675 | |
| -1 | -2,224,675 |
Now, we try dividing 2,224,675 by 3:
2,224,675 ÷ 3 = 741,558.3333
If the quotient is a whole number, then 3 and 741,558.3333 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 | 2,224,675 | |
| -1 | -2,224,675 |
Let's try dividing by 4:
2,224,675 ÷ 4 = 556,168.75
If the quotient is a whole number, then 4 and 556,168.75 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 | 2,224,675 | |
| -1 | 2,224,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 53 | 73 | 115 | 265 | 365 | 575 | 1,219 | 1,325 | 1,679 | 1,825 | 3,869 | 6,095 | 8,395 | 19,345 | 30,475 | 41,975 | 88,987 | 96,725 | 444,935 | 2,224,675 |
| -1 | -5 | -23 | -25 | -53 | -73 | -115 | -265 | -365 | -575 | -1,219 | -1,325 | -1,679 | -1,825 | -3,869 | -6,095 | -8,395 | -19,345 | -30,475 | -41,975 | -88,987 | -96,725 | -444,935 | -2,224,675 |
