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 647,714,167, 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 | 647,714,167 | |
-1 | -647,714,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 647,714,167.
Example:
1 x 647,714,167 = 647,714,167
and
-1 x -647,714,167 = 647,714,167
Notice both answers equal 647,714,167
With that explanation out of the way, let's continue. Next, we take the number 647,714,167 and divide it by 2:
647,714,167 ÷ 2 = 323,857,083.5
If the quotient is a whole number, then 2 and 323,857,083.5 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 | 647,714,167 | |
-1 | -647,714,167 |
Now, we try dividing 647,714,167 by 3:
647,714,167 ÷ 3 = 215,904,722.3333
If the quotient is a whole number, then 3 and 215,904,722.3333 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 | 647,714,167 | |
-1 | -647,714,167 |
Let's try dividing by 4:
647,714,167 ÷ 4 = 161,928,541.75
If the quotient is a whole number, then 4 and 161,928,541.75 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 | 647,714,167 | |
-1 | 647,714,167 |
If you did it right, you will end up with this table:
1 | 5,413 | 119,659 | 647,714,167 |
-1 | -5,413 | -119,659 | -647,714,167 |
