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 74,312,063, 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 | 74,312,063 | |
| -1 | -74,312,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,312,063.
Example:
1 x 74,312,063 = 74,312,063
and
-1 x -74,312,063 = 74,312,063
Notice both answers equal 74,312,063
With that explanation out of the way, let's continue. Next, we take the number 74,312,063 and divide it by 2:
74,312,063 ÷ 2 = 37,156,031.5
If the quotient is a whole number, then 2 and 37,156,031.5 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 | 74,312,063 | |
| -1 | -74,312,063 |
Now, we try dividing 74,312,063 by 3:
74,312,063 ÷ 3 = 24,770,687.6667
If the quotient is a whole number, then 3 and 24,770,687.6667 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 | 74,312,063 | |
| -1 | -74,312,063 |
Let's try dividing by 4:
74,312,063 ÷ 4 = 18,578,015.75
If the quotient is a whole number, then 4 and 18,578,015.75 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 | 74,312,063 | |
| -1 | 74,312,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 101 | 623 | 707 | 1,181 | 8,267 | 8,989 | 62,923 | 105,109 | 119,281 | 735,763 | 834,967 | 10,616,009 | 74,312,063 |
| -1 | -7 | -89 | -101 | -623 | -707 | -1,181 | -8,267 | -8,989 | -62,923 | -105,109 | -119,281 | -735,763 | -834,967 | -10,616,009 | -74,312,063 |
