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 2,125,961, 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 | 2,125,961 | |
-1 | -2,125,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,125,961.
Example:
1 x 2,125,961 = 2,125,961
and
-1 x -2,125,961 = 2,125,961
Notice both answers equal 2,125,961
With that explanation out of the way, let's continue. Next, we take the number 2,125,961 and divide it by 2:
2,125,961 ÷ 2 = 1,062,980.5
If the quotient is a whole number, then 2 and 1,062,980.5 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 | 2,125,961 | |
-1 | -2,125,961 |
Now, we try dividing 2,125,961 by 3:
2,125,961 ÷ 3 = 708,653.6667
If the quotient is a whole number, then 3 and 708,653.6667 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 | 2,125,961 | |
-1 | -2,125,961 |
Let's try dividing by 4:
2,125,961 ÷ 4 = 531,490.25
If the quotient is a whole number, then 4 and 531,490.25 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 | 2,125,961 | |
-1 | 2,125,961 |
If you did it right, you will end up with this table:
1 | 29 | 73,309 | 2,125,961 |
-1 | -29 | -73,309 | -2,125,961 |
