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 2,961,571, 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 | 2,961,571 | |
-1 | -2,961,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,961,571.
Example:
1 x 2,961,571 = 2,961,571
and
-1 x -2,961,571 = 2,961,571
Notice both answers equal 2,961,571
With that explanation out of the way, let's continue. Next, we take the number 2,961,571 and divide it by 2:
2,961,571 ÷ 2 = 1,480,785.5
If the quotient is a whole number, then 2 and 1,480,785.5 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 | 2,961,571 | |
-1 | -2,961,571 |
Now, we try dividing 2,961,571 by 3:
2,961,571 ÷ 3 = 987,190.3333
If the quotient is a whole number, then 3 and 987,190.3333 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 | 2,961,571 | |
-1 | -2,961,571 |
Let's try dividing by 4:
2,961,571 ÷ 4 = 740,392.75
If the quotient is a whole number, then 4 and 740,392.75 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 | 2,961,571 | |
-1 | 2,961,571 |
If you did it right, you will end up with this table:
1 | 1,553 | 1,907 | 2,961,571 |
-1 | -1,553 | -1,907 | -2,961,571 |
