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 2,479,273, 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 | 2,479,273 | |
-1 | -2,479,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,479,273.
Example:
1 x 2,479,273 = 2,479,273
and
-1 x -2,479,273 = 2,479,273
Notice both answers equal 2,479,273
With that explanation out of the way, let's continue. Next, we take the number 2,479,273 and divide it by 2:
2,479,273 ÷ 2 = 1,239,636.5
If the quotient is a whole number, then 2 and 1,239,636.5 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 | 2,479,273 | |
-1 | -2,479,273 |
Now, we try dividing 2,479,273 by 3:
2,479,273 ÷ 3 = 826,424.3333
If the quotient is a whole number, then 3 and 826,424.3333 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 | 2,479,273 | |
-1 | -2,479,273 |
Let's try dividing by 4:
2,479,273 ÷ 4 = 619,818.25
If the quotient is a whole number, then 4 and 619,818.25 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 | 2,479,273 | |
-1 | 2,479,273 |
If you did it right, you will end up with this table:
1 | 89 | 313 | 7,921 | 27,857 | 2,479,273 |
-1 | -89 | -313 | -7,921 | -27,857 | -2,479,273 |
