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 73,370,045, 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 | 73,370,045 | |
| -1 | -73,370,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,370,045.
Example:
1 x 73,370,045 = 73,370,045
and
-1 x -73,370,045 = 73,370,045
Notice both answers equal 73,370,045
With that explanation out of the way, let's continue. Next, we take the number 73,370,045 and divide it by 2:
73,370,045 ÷ 2 = 36,685,022.5
If the quotient is a whole number, then 2 and 36,685,022.5 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 | 73,370,045 | |
| -1 | -73,370,045 |
Now, we try dividing 73,370,045 by 3:
73,370,045 ÷ 3 = 24,456,681.6667
If the quotient is a whole number, then 3 and 24,456,681.6667 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 | 73,370,045 | |
| -1 | -73,370,045 |
Let's try dividing by 4:
73,370,045 ÷ 4 = 18,342,511.25
If the quotient is a whole number, then 4 and 18,342,511.25 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 | 73,370,045 | |
| -1 | 73,370,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 123,311 | 616,555 | 863,177 | 2,096,287 | 4,315,885 | 10,481,435 | 14,674,009 | 73,370,045 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -123,311 | -616,555 | -863,177 | -2,096,287 | -4,315,885 | -10,481,435 | -14,674,009 | -73,370,045 |
