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 62,417,921, 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 | 62,417,921 | |
-1 | -62,417,921 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,417,921.
Example:
1 x 62,417,921 = 62,417,921
and
-1 x -62,417,921 = 62,417,921
Notice both answers equal 62,417,921
With that explanation out of the way, let's continue. Next, we take the number 62,417,921 and divide it by 2:
62,417,921 ÷ 2 = 31,208,960.5
If the quotient is a whole number, then 2 and 31,208,960.5 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 | 62,417,921 | |
-1 | -62,417,921 |
Now, we try dividing 62,417,921 by 3:
62,417,921 ÷ 3 = 20,805,973.6667
If the quotient is a whole number, then 3 and 20,805,973.6667 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 | 62,417,921 | |
-1 | -62,417,921 |
Let's try dividing by 4:
62,417,921 ÷ 4 = 15,604,480.25
If the quotient is a whole number, then 4 and 15,604,480.25 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 | 62,417,921 | |
-1 | 62,417,921 |
If you did it right, you will end up with this table:
1 | 2,269 | 27,509 | 62,417,921 |
-1 | -2,269 | -27,509 | -62,417,921 |
