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 220,304,539, 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 | 220,304,539 | |
| -1 | -220,304,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,304,539.
Example:
1 x 220,304,539 = 220,304,539
and
-1 x -220,304,539 = 220,304,539
Notice both answers equal 220,304,539
With that explanation out of the way, let's continue. Next, we take the number 220,304,539 and divide it by 2:
220,304,539 ÷ 2 = 110,152,269.5
If the quotient is a whole number, then 2 and 110,152,269.5 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 | 220,304,539 | |
| -1 | -220,304,539 |
Now, we try dividing 220,304,539 by 3:
220,304,539 ÷ 3 = 73,434,846.3333
If the quotient is a whole number, then 3 and 73,434,846.3333 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 | 220,304,539 | |
| -1 | -220,304,539 |
Let's try dividing by 4:
220,304,539 ÷ 4 = 55,076,134.75
If the quotient is a whole number, then 4 and 55,076,134.75 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 | 220,304,539 | |
| -1 | 220,304,539 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 317 | 637 | 1,091 | 2,219 | 4,121 | 7,637 | 14,183 | 15,533 | 28,847 | 53,459 | 99,281 | 201,929 | 345,847 | 694,967 | 2,420,929 | 4,496,011 | 16,946,503 | 31,472,077 | 220,304,539 |
| -1 | -7 | -13 | -49 | -91 | -317 | -637 | -1,091 | -2,219 | -4,121 | -7,637 | -14,183 | -15,533 | -28,847 | -53,459 | -99,281 | -201,929 | -345,847 | -694,967 | -2,420,929 | -4,496,011 | -16,946,503 | -31,472,077 | -220,304,539 |
