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 220,542,275, 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 | 220,542,275 | |
| -1 | -220,542,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,542,275.
Example:
1 x 220,542,275 = 220,542,275
and
-1 x -220,542,275 = 220,542,275
Notice both answers equal 220,542,275
With that explanation out of the way, let's continue. Next, we take the number 220,542,275 and divide it by 2:
220,542,275 ÷ 2 = 110,271,137.5
If the quotient is a whole number, then 2 and 110,271,137.5 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 | 220,542,275 | |
| -1 | -220,542,275 |
Now, we try dividing 220,542,275 by 3:
220,542,275 ÷ 3 = 73,514,091.6667
If the quotient is a whole number, then 3 and 73,514,091.6667 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 | 220,542,275 | |
| -1 | -220,542,275 |
Let's try dividing by 4:
220,542,275 ÷ 4 = 55,135,568.75
If the quotient is a whole number, then 4 and 55,135,568.75 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 | 220,542,275 | |
| -1 | 220,542,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 53 | 85 | 265 | 425 | 901 | 1,325 | 4,505 | 9,791 | 22,525 | 48,955 | 166,447 | 244,775 | 518,923 | 832,235 | 2,594,615 | 4,161,175 | 8,821,691 | 12,973,075 | 44,108,455 | 220,542,275 |
| -1 | -5 | -17 | -25 | -53 | -85 | -265 | -425 | -901 | -1,325 | -4,505 | -9,791 | -22,525 | -48,955 | -166,447 | -244,775 | -518,923 | -832,235 | -2,594,615 | -4,161,175 | -8,821,691 | -12,973,075 | -44,108,455 | -220,542,275 |
