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 54,720,701, 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 | 54,720,701 | |
-1 | -54,720,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,720,701.
Example:
1 x 54,720,701 = 54,720,701
and
-1 x -54,720,701 = 54,720,701
Notice both answers equal 54,720,701
With that explanation out of the way, let's continue. Next, we take the number 54,720,701 and divide it by 2:
54,720,701 ÷ 2 = 27,360,350.5
If the quotient is a whole number, then 2 and 27,360,350.5 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 | 54,720,701 | |
-1 | -54,720,701 |
Now, we try dividing 54,720,701 by 3:
54,720,701 ÷ 3 = 18,240,233.6667
If the quotient is a whole number, then 3 and 18,240,233.6667 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 | 54,720,701 | |
-1 | -54,720,701 |
Let's try dividing by 4:
54,720,701 ÷ 4 = 13,680,175.25
If the quotient is a whole number, then 4 and 13,680,175.25 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 | 54,720,701 | |
-1 | 54,720,701 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 1,116,749 | 7,817,243 | 54,720,701 |
-1 | -7 | -49 | -1,116,749 | -7,817,243 | -54,720,701 |
