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 2,718,403, 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 | 2,718,403 | |
-1 | -2,718,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,718,403.
Example:
1 x 2,718,403 = 2,718,403
and
-1 x -2,718,403 = 2,718,403
Notice both answers equal 2,718,403
With that explanation out of the way, let's continue. Next, we take the number 2,718,403 and divide it by 2:
2,718,403 ÷ 2 = 1,359,201.5
If the quotient is a whole number, then 2 and 1,359,201.5 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 | 2,718,403 | |
-1 | -2,718,403 |
Now, we try dividing 2,718,403 by 3:
2,718,403 ÷ 3 = 906,134.3333
If the quotient is a whole number, then 3 and 906,134.3333 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 | 2,718,403 | |
-1 | -2,718,403 |
Let's try dividing by 4:
2,718,403 ÷ 4 = 679,600.75
If the quotient is a whole number, then 4 and 679,600.75 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 | 2,718,403 | |
-1 | 2,718,403 |
If you did it right, you will end up with this table:
1 | 197 | 13,799 | 2,718,403 |
-1 | -197 | -13,799 | -2,718,403 |
