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 72,000,635, 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 | 72,000,635 | |
| -1 | -72,000,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,000,635.
Example:
1 x 72,000,635 = 72,000,635
and
-1 x -72,000,635 = 72,000,635
Notice both answers equal 72,000,635
With that explanation out of the way, let's continue. Next, we take the number 72,000,635 and divide it by 2:
72,000,635 ÷ 2 = 36,000,317.5
If the quotient is a whole number, then 2 and 36,000,317.5 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 | 72,000,635 | |
| -1 | -72,000,635 |
Now, we try dividing 72,000,635 by 3:
72,000,635 ÷ 3 = 24,000,211.6667
If the quotient is a whole number, then 3 and 24,000,211.6667 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 | 72,000,635 | |
| -1 | -72,000,635 |
Let's try dividing by 4:
72,000,635 ÷ 4 = 18,000,158.75
If the quotient is a whole number, then 4 and 18,000,158.75 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 | 72,000,635 | |
| -1 | 72,000,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 271 | 1,355 | 1,897 | 7,591 | 9,485 | 37,955 | 53,137 | 265,685 | 2,057,161 | 10,285,805 | 14,400,127 | 72,000,635 |
| -1 | -5 | -7 | -35 | -271 | -1,355 | -1,897 | -7,591 | -9,485 | -37,955 | -53,137 | -265,685 | -2,057,161 | -10,285,805 | -14,400,127 | -72,000,635 |
