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 7,154,365, 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 | 7,154,365 | |
| -1 | -7,154,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,154,365.
Example:
1 x 7,154,365 = 7,154,365
and
-1 x -7,154,365 = 7,154,365
Notice both answers equal 7,154,365
With that explanation out of the way, let's continue. Next, we take the number 7,154,365 and divide it by 2:
7,154,365 ÷ 2 = 3,577,182.5
If the quotient is a whole number, then 2 and 3,577,182.5 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 | 7,154,365 | |
| -1 | -7,154,365 |
Now, we try dividing 7,154,365 by 3:
7,154,365 ÷ 3 = 2,384,788.3333
If the quotient is a whole number, then 3 and 2,384,788.3333 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 | 7,154,365 | |
| -1 | -7,154,365 |
Let's try dividing by 4:
7,154,365 ÷ 4 = 1,788,591.25
If the quotient is a whole number, then 4 and 1,788,591.25 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 | 7,154,365 | |
| -1 | 7,154,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 73 | 85 | 365 | 1,153 | 1,241 | 5,765 | 6,205 | 19,601 | 84,169 | 98,005 | 420,845 | 1,430,873 | 7,154,365 |
| -1 | -5 | -17 | -73 | -85 | -365 | -1,153 | -1,241 | -5,765 | -6,205 | -19,601 | -84,169 | -98,005 | -420,845 | -1,430,873 | -7,154,365 |
