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 42,445,445, 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 | 42,445,445 | |
| -1 | -42,445,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,445,445.
Example:
1 x 42,445,445 = 42,445,445
and
-1 x -42,445,445 = 42,445,445
Notice both answers equal 42,445,445
With that explanation out of the way, let's continue. Next, we take the number 42,445,445 and divide it by 2:
42,445,445 ÷ 2 = 21,222,722.5
If the quotient is a whole number, then 2 and 21,222,722.5 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 | 42,445,445 | |
| -1 | -42,445,445 |
Now, we try dividing 42,445,445 by 3:
42,445,445 ÷ 3 = 14,148,481.6667
If the quotient is a whole number, then 3 and 14,148,481.6667 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 | 42,445,445 | |
| -1 | -42,445,445 |
Let's try dividing by 4:
42,445,445 ÷ 4 = 10,611,361.25
If the quotient is a whole number, then 4 and 10,611,361.25 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 | 42,445,445 | |
| -1 | 42,445,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 293 | 1,465 | 2,051 | 4,139 | 10,255 | 20,695 | 28,973 | 144,865 | 1,212,727 | 6,063,635 | 8,489,089 | 42,445,445 |
| -1 | -5 | -7 | -35 | -293 | -1,465 | -2,051 | -4,139 | -10,255 | -20,695 | -28,973 | -144,865 | -1,212,727 | -6,063,635 | -8,489,089 | -42,445,445 |
