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 47,436,445, 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 | 47,436,445 | |
| -1 | -47,436,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,436,445.
Example:
1 x 47,436,445 = 47,436,445
and
-1 x -47,436,445 = 47,436,445
Notice both answers equal 47,436,445
With that explanation out of the way, let's continue. Next, we take the number 47,436,445 and divide it by 2:
47,436,445 ÷ 2 = 23,718,222.5
If the quotient is a whole number, then 2 and 23,718,222.5 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 | 47,436,445 | |
| -1 | -47,436,445 |
Now, we try dividing 47,436,445 by 3:
47,436,445 ÷ 3 = 15,812,148.3333
If the quotient is a whole number, then 3 and 15,812,148.3333 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 | 47,436,445 | |
| -1 | -47,436,445 |
Let's try dividing by 4:
47,436,445 ÷ 4 = 11,859,111.25
If the quotient is a whole number, then 4 and 11,859,111.25 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 | 47,436,445 | |
| -1 | 47,436,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 71,333 | 356,665 | 499,331 | 1,355,327 | 2,496,655 | 6,776,635 | 9,487,289 | 47,436,445 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -71,333 | -356,665 | -499,331 | -1,355,327 | -2,496,655 | -6,776,635 | -9,487,289 | -47,436,445 |
