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 63,013,555, 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 | 63,013,555 | |
| -1 | -63,013,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,013,555.
Example:
1 x 63,013,555 = 63,013,555
and
-1 x -63,013,555 = 63,013,555
Notice both answers equal 63,013,555
With that explanation out of the way, let's continue. Next, we take the number 63,013,555 and divide it by 2:
63,013,555 ÷ 2 = 31,506,777.5
If the quotient is a whole number, then 2 and 31,506,777.5 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 | 63,013,555 | |
| -1 | -63,013,555 |
Now, we try dividing 63,013,555 by 3:
63,013,555 ÷ 3 = 21,004,518.3333
If the quotient is a whole number, then 3 and 21,004,518.3333 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 | 63,013,555 | |
| -1 | -63,013,555 |
Let's try dividing by 4:
63,013,555 ÷ 4 = 15,753,388.75
If the quotient is a whole number, then 4 and 15,753,388.75 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 | 63,013,555 | |
| -1 | 63,013,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 21,617 | 108,085 | 237,787 | 1,145,701 | 1,188,935 | 5,728,505 | 12,602,711 | 63,013,555 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -21,617 | -108,085 | -237,787 | -1,145,701 | -1,188,935 | -5,728,505 | -12,602,711 | -63,013,555 |
