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 63,530,275, 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 | 63,530,275 | |
| -1 | -63,530,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,530,275.
Example:
1 x 63,530,275 = 63,530,275
and
-1 x -63,530,275 = 63,530,275
Notice both answers equal 63,530,275
With that explanation out of the way, let's continue. Next, we take the number 63,530,275 and divide it by 2:
63,530,275 ÷ 2 = 31,765,137.5
If the quotient is a whole number, then 2 and 31,765,137.5 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 | 63,530,275 | |
| -1 | -63,530,275 |
Now, we try dividing 63,530,275 by 3:
63,530,275 ÷ 3 = 21,176,758.3333
If the quotient is a whole number, then 3 and 21,176,758.3333 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 | 63,530,275 | |
| -1 | -63,530,275 |
Let's try dividing by 4:
63,530,275 ÷ 4 = 15,882,568.75
If the quotient is a whole number, then 4 and 15,882,568.75 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 | 63,530,275 | |
| -1 | 63,530,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 83 | 85 | 415 | 425 | 1,411 | 1,801 | 2,075 | 7,055 | 9,005 | 30,617 | 35,275 | 45,025 | 149,483 | 153,085 | 747,415 | 765,425 | 2,541,211 | 3,737,075 | 12,706,055 | 63,530,275 |
| -1 | -5 | -17 | -25 | -83 | -85 | -415 | -425 | -1,411 | -1,801 | -2,075 | -7,055 | -9,005 | -30,617 | -35,275 | -45,025 | -149,483 | -153,085 | -747,415 | -765,425 | -2,541,211 | -3,737,075 | -12,706,055 | -63,530,275 |
