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 74,193,295, 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 | 74,193,295 | |
| -1 | -74,193,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,193,295.
Example:
1 x 74,193,295 = 74,193,295
and
-1 x -74,193,295 = 74,193,295
Notice both answers equal 74,193,295
With that explanation out of the way, let's continue. Next, we take the number 74,193,295 and divide it by 2:
74,193,295 ÷ 2 = 37,096,647.5
If the quotient is a whole number, then 2 and 37,096,647.5 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 | 74,193,295 | |
| -1 | -74,193,295 |
Now, we try dividing 74,193,295 by 3:
74,193,295 ÷ 3 = 24,731,098.3333
If the quotient is a whole number, then 3 and 24,731,098.3333 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 | 74,193,295 | |
| -1 | -74,193,295 |
Let's try dividing by 4:
74,193,295 ÷ 4 = 18,548,323.75
If the quotient is a whole number, then 4 and 18,548,323.75 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 | 74,193,295 | |
| -1 | 74,193,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,103 | 1,223 | 5,515 | 6,115 | 12,133 | 13,453 | 60,665 | 67,265 | 1,348,969 | 6,744,845 | 14,838,659 | 74,193,295 |
| -1 | -5 | -11 | -55 | -1,103 | -1,223 | -5,515 | -6,115 | -12,133 | -13,453 | -60,665 | -67,265 | -1,348,969 | -6,744,845 | -14,838,659 | -74,193,295 |
