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 61,001,455, 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 | 61,001,455 | |
-1 | -61,001,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,001,455.
Example:
1 x 61,001,455 = 61,001,455
and
-1 x -61,001,455 = 61,001,455
Notice both answers equal 61,001,455
With that explanation out of the way, let's continue. Next, we take the number 61,001,455 and divide it by 2:
61,001,455 ÷ 2 = 30,500,727.5
If the quotient is a whole number, then 2 and 30,500,727.5 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 | 61,001,455 | |
-1 | -61,001,455 |
Now, we try dividing 61,001,455 by 3:
61,001,455 ÷ 3 = 20,333,818.3333
If the quotient is a whole number, then 3 and 20,333,818.3333 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 | 61,001,455 | |
-1 | -61,001,455 |
Let's try dividing by 4:
61,001,455 ÷ 4 = 15,250,363.75
If the quotient is a whole number, then 4 and 15,250,363.75 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 | 61,001,455 | |
-1 | 61,001,455 |
If you did it right, you will end up with this table:
1 | 5 | 12,200,291 | 61,001,455 |
-1 | -5 | -12,200,291 | -61,001,455 |
