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 542,525,347, 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 | 542,525,347 | |
| -1 | -542,525,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,525,347.
Example:
1 x 542,525,347 = 542,525,347
and
-1 x -542,525,347 = 542,525,347
Notice both answers equal 542,525,347
With that explanation out of the way, let's continue. Next, we take the number 542,525,347 and divide it by 2:
542,525,347 ÷ 2 = 271,262,673.5
If the quotient is a whole number, then 2 and 271,262,673.5 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 | 542,525,347 | |
| -1 | -542,525,347 |
Now, we try dividing 542,525,347 by 3:
542,525,347 ÷ 3 = 180,841,782.3333
If the quotient is a whole number, then 3 and 180,841,782.3333 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 | 542,525,347 | |
| -1 | -542,525,347 |
Let's try dividing by 4:
542,525,347 ÷ 4 = 135,631,336.75
If the quotient is a whole number, then 4 and 135,631,336.75 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 | 542,525,347 | |
| -1 | 542,525,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 353 | 2,471 | 4,589 | 16,889 | 32,123 | 118,223 | 219,557 | 1,536,899 | 5,961,817 | 41,732,719 | 77,503,621 | 542,525,347 |
| -1 | -7 | -13 | -91 | -353 | -2,471 | -4,589 | -16,889 | -32,123 | -118,223 | -219,557 | -1,536,899 | -5,961,817 | -41,732,719 | -77,503,621 | -542,525,347 |
