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 45,030,349, 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 | 45,030,349 | |
| -1 | -45,030,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,030,349.
Example:
1 x 45,030,349 = 45,030,349
and
-1 x -45,030,349 = 45,030,349
Notice both answers equal 45,030,349
With that explanation out of the way, let's continue. Next, we take the number 45,030,349 and divide it by 2:
45,030,349 ÷ 2 = 22,515,174.5
If the quotient is a whole number, then 2 and 22,515,174.5 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 | 45,030,349 | |
| -1 | -45,030,349 |
Now, we try dividing 45,030,349 by 3:
45,030,349 ÷ 3 = 15,010,116.3333
If the quotient is a whole number, then 3 and 15,010,116.3333 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 | 45,030,349 | |
| -1 | -45,030,349 |
Let's try dividing by 4:
45,030,349 ÷ 4 = 11,257,587.25
If the quotient is a whole number, then 4 and 11,257,587.25 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 | 45,030,349 | |
| -1 | 45,030,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 419 | 1,181 | 2,933 | 5,447 | 8,267 | 15,353 | 38,129 | 107,471 | 494,839 | 3,463,873 | 6,432,907 | 45,030,349 |
| -1 | -7 | -13 | -91 | -419 | -1,181 | -2,933 | -5,447 | -8,267 | -15,353 | -38,129 | -107,471 | -494,839 | -3,463,873 | -6,432,907 | -45,030,349 |
