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 487,758,607, 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 | 487,758,607 | |
-1 | -487,758,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 487,758,607.
Example:
1 x 487,758,607 = 487,758,607
and
-1 x -487,758,607 = 487,758,607
Notice both answers equal 487,758,607
With that explanation out of the way, let's continue. Next, we take the number 487,758,607 and divide it by 2:
487,758,607 ÷ 2 = 243,879,303.5
If the quotient is a whole number, then 2 and 243,879,303.5 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 | 487,758,607 | |
-1 | -487,758,607 |
Now, we try dividing 487,758,607 by 3:
487,758,607 ÷ 3 = 162,586,202.3333
If the quotient is a whole number, then 3 and 162,586,202.3333 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 | 487,758,607 | |
-1 | -487,758,607 |
Let's try dividing by 4:
487,758,607 ÷ 4 = 121,939,651.75
If the quotient is a whole number, then 4 and 121,939,651.75 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 | 487,758,607 | |
-1 | 487,758,607 |
If you did it right, you will end up with this table:
1 | 7 | 69,679,801 | 487,758,607 |
-1 | -7 | -69,679,801 | -487,758,607 |
