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 541,154,635, 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 | 541,154,635 | |
| -1 | -541,154,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,154,635.
Example:
1 x 541,154,635 = 541,154,635
and
-1 x -541,154,635 = 541,154,635
Notice both answers equal 541,154,635
With that explanation out of the way, let's continue. Next, we take the number 541,154,635 and divide it by 2:
541,154,635 ÷ 2 = 270,577,317.5
If the quotient is a whole number, then 2 and 270,577,317.5 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 | 541,154,635 | |
| -1 | -541,154,635 |
Now, we try dividing 541,154,635 by 3:
541,154,635 ÷ 3 = 180,384,878.3333
If the quotient is a whole number, then 3 and 180,384,878.3333 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 | 541,154,635 | |
| -1 | -541,154,635 |
Let's try dividing by 4:
541,154,635 ÷ 4 = 135,288,658.75
If the quotient is a whole number, then 4 and 135,288,658.75 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 | 541,154,635 | |
| -1 | 541,154,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 641 | 3,205 | 4,487 | 22,435 | 24,121 | 120,605 | 168,847 | 844,235 | 15,461,561 | 77,307,805 | 108,230,927 | 541,154,635 |
| -1 | -5 | -7 | -35 | -641 | -3,205 | -4,487 | -22,435 | -24,121 | -120,605 | -168,847 | -844,235 | -15,461,561 | -77,307,805 | -108,230,927 | -541,154,635 |
