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 55,112,261, 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 | 55,112,261 | |
-1 | -55,112,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,112,261.
Example:
1 x 55,112,261 = 55,112,261
and
-1 x -55,112,261 = 55,112,261
Notice both answers equal 55,112,261
With that explanation out of the way, let's continue. Next, we take the number 55,112,261 and divide it by 2:
55,112,261 ÷ 2 = 27,556,130.5
If the quotient is a whole number, then 2 and 27,556,130.5 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 | 55,112,261 | |
-1 | -55,112,261 |
Now, we try dividing 55,112,261 by 3:
55,112,261 ÷ 3 = 18,370,753.6667
If the quotient is a whole number, then 3 and 18,370,753.6667 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 | 55,112,261 | |
-1 | -55,112,261 |
Let's try dividing by 4:
55,112,261 ÷ 4 = 13,778,065.25
If the quotient is a whole number, then 4 and 13,778,065.25 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 | 55,112,261 | |
-1 | 55,112,261 |
If you did it right, you will end up with this table:
1 | 1,439 | 38,299 | 55,112,261 |
-1 | -1,439 | -38,299 | -55,112,261 |
