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 71,486,201, 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 | 71,486,201 | |
-1 | -71,486,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,486,201.
Example:
1 x 71,486,201 = 71,486,201
and
-1 x -71,486,201 = 71,486,201
Notice both answers equal 71,486,201
With that explanation out of the way, let's continue. Next, we take the number 71,486,201 and divide it by 2:
71,486,201 ÷ 2 = 35,743,100.5
If the quotient is a whole number, then 2 and 35,743,100.5 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 | 71,486,201 | |
-1 | -71,486,201 |
Now, we try dividing 71,486,201 by 3:
71,486,201 ÷ 3 = 23,828,733.6667
If the quotient is a whole number, then 3 and 23,828,733.6667 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 | 71,486,201 | |
-1 | -71,486,201 |
Let's try dividing by 4:
71,486,201 ÷ 4 = 17,871,550.25
If the quotient is a whole number, then 4 and 17,871,550.25 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 | 71,486,201 | |
-1 | 71,486,201 |
If you did it right, you will end up with this table:
1 | 47 | 1,520,983 | 71,486,201 |
-1 | -47 | -1,520,983 | -71,486,201 |
