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 34,290,445, 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 | 34,290,445 | |
| -1 | -34,290,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,290,445.
Example:
1 x 34,290,445 = 34,290,445
and
-1 x -34,290,445 = 34,290,445
Notice both answers equal 34,290,445
With that explanation out of the way, let's continue. Next, we take the number 34,290,445 and divide it by 2:
34,290,445 ÷ 2 = 17,145,222.5
If the quotient is a whole number, then 2 and 17,145,222.5 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 | 34,290,445 | |
| -1 | -34,290,445 |
Now, we try dividing 34,290,445 by 3:
34,290,445 ÷ 3 = 11,430,148.3333
If the quotient is a whole number, then 3 and 11,430,148.3333 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 | 34,290,445 | |
| -1 | -34,290,445 |
Let's try dividing by 4:
34,290,445 ÷ 4 = 8,572,611.25
If the quotient is a whole number, then 4 and 8,572,611.25 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 | 34,290,445 | |
| -1 | 34,290,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 4,165 | 8,233 | 41,165 | 57,631 | 139,961 | 288,155 | 403,417 | 699,805 | 979,727 | 2,017,085 | 4,898,635 | 6,858,089 | 34,290,445 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -4,165 | -8,233 | -41,165 | -57,631 | -139,961 | -288,155 | -403,417 | -699,805 | -979,727 | -2,017,085 | -4,898,635 | -6,858,089 | -34,290,445 |
