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 74,363,555, 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 | 74,363,555 | |
| -1 | -74,363,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,363,555.
Example:
1 x 74,363,555 = 74,363,555
and
-1 x -74,363,555 = 74,363,555
Notice both answers equal 74,363,555
With that explanation out of the way, let's continue. Next, we take the number 74,363,555 and divide it by 2:
74,363,555 ÷ 2 = 37,181,777.5
If the quotient is a whole number, then 2 and 37,181,777.5 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 | 74,363,555 | |
| -1 | -74,363,555 |
Now, we try dividing 74,363,555 by 3:
74,363,555 ÷ 3 = 24,787,851.6667
If the quotient is a whole number, then 3 and 24,787,851.6667 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 | 74,363,555 | |
| -1 | -74,363,555 |
Let's try dividing by 4:
74,363,555 ÷ 4 = 18,590,888.75
If the quotient is a whole number, then 4 and 18,590,888.75 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 | 74,363,555 | |
| -1 | 74,363,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 49,411 | 247,055 | 345,877 | 1,729,385 | 2,124,673 | 10,623,365 | 14,872,711 | 74,363,555 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -49,411 | -247,055 | -345,877 | -1,729,385 | -2,124,673 | -10,623,365 | -14,872,711 | -74,363,555 |
