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 543,740,071, 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 | 543,740,071 | |
| -1 | -543,740,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,740,071.
Example:
1 x 543,740,071 = 543,740,071
and
-1 x -543,740,071 = 543,740,071
Notice both answers equal 543,740,071
With that explanation out of the way, let's continue. Next, we take the number 543,740,071 and divide it by 2:
543,740,071 ÷ 2 = 271,870,035.5
If the quotient is a whole number, then 2 and 271,870,035.5 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 | 543,740,071 | |
| -1 | -543,740,071 |
Now, we try dividing 543,740,071 by 3:
543,740,071 ÷ 3 = 181,246,690.3333
If the quotient is a whole number, then 3 and 181,246,690.3333 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 | 543,740,071 | |
| -1 | -543,740,071 |
Let's try dividing by 4:
543,740,071 ÷ 4 = 135,935,017.75
If the quotient is a whole number, then 4 and 135,935,017.75 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 | 543,740,071 | |
| -1 | 543,740,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 419 | 623 | 2,083 | 2,933 | 14,581 | 37,291 | 185,387 | 261,037 | 872,777 | 1,297,709 | 6,109,439 | 77,677,153 | 543,740,071 |
| -1 | -7 | -89 | -419 | -623 | -2,083 | -2,933 | -14,581 | -37,291 | -185,387 | -261,037 | -872,777 | -1,297,709 | -6,109,439 | -77,677,153 | -543,740,071 |
