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 671,414,525, 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 | 671,414,525 | |
| -1 | -671,414,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 671,414,525.
Example:
1 x 671,414,525 = 671,414,525
and
-1 x -671,414,525 = 671,414,525
Notice both answers equal 671,414,525
With that explanation out of the way, let's continue. Next, we take the number 671,414,525 and divide it by 2:
671,414,525 ÷ 2 = 335,707,262.5
If the quotient is a whole number, then 2 and 335,707,262.5 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 | 671,414,525 | |
| -1 | -671,414,525 |
Now, we try dividing 671,414,525 by 3:
671,414,525 ÷ 3 = 223,804,841.6667
If the quotient is a whole number, then 3 and 223,804,841.6667 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 | 671,414,525 | |
| -1 | -671,414,525 |
Let's try dividing by 4:
671,414,525 ÷ 4 = 167,853,631.25
If the quotient is a whole number, then 4 and 167,853,631.25 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 | 671,414,525 | |
| -1 | 671,414,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 145 | 725 | 926,089 | 4,630,445 | 23,152,225 | 26,856,581 | 134,282,905 | 671,414,525 |
| -1 | -5 | -25 | -29 | -145 | -725 | -926,089 | -4,630,445 | -23,152,225 | -26,856,581 | -134,282,905 | -671,414,525 |
