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 63,641,431, 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 | 63,641,431 | |
| -1 | -63,641,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,641,431.
Example:
1 x 63,641,431 = 63,641,431
and
-1 x -63,641,431 = 63,641,431
Notice both answers equal 63,641,431
With that explanation out of the way, let's continue. Next, we take the number 63,641,431 and divide it by 2:
63,641,431 ÷ 2 = 31,820,715.5
If the quotient is a whole number, then 2 and 31,820,715.5 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 | 63,641,431 | |
| -1 | -63,641,431 |
Now, we try dividing 63,641,431 by 3:
63,641,431 ÷ 3 = 21,213,810.3333
If the quotient is a whole number, then 3 and 21,213,810.3333 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 | 63,641,431 | |
| -1 | -63,641,431 |
Let's try dividing by 4:
63,641,431 ÷ 4 = 15,910,357.75
If the quotient is a whole number, then 4 and 15,910,357.75 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 | 63,641,431 | |
| -1 | 63,641,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 47 | 133 | 329 | 893 | 6,251 | 10,181 | 71,267 | 193,439 | 478,507 | 1,354,073 | 3,349,549 | 9,091,633 | 63,641,431 |
| -1 | -7 | -19 | -47 | -133 | -329 | -893 | -6,251 | -10,181 | -71,267 | -193,439 | -478,507 | -1,354,073 | -3,349,549 | -9,091,633 | -63,641,431 |
