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 79,177,495, 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 | 79,177,495 | |
| -1 | -79,177,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,177,495.
Example:
1 x 79,177,495 = 79,177,495
and
-1 x -79,177,495 = 79,177,495
Notice both answers equal 79,177,495
With that explanation out of the way, let's continue. Next, we take the number 79,177,495 and divide it by 2:
79,177,495 ÷ 2 = 39,588,747.5
If the quotient is a whole number, then 2 and 39,588,747.5 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 | 79,177,495 | |
| -1 | -79,177,495 |
Now, we try dividing 79,177,495 by 3:
79,177,495 ÷ 3 = 26,392,498.3333
If the quotient is a whole number, then 3 and 26,392,498.3333 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 | 79,177,495 | |
| -1 | -79,177,495 |
Let's try dividing by 4:
79,177,495 ÷ 4 = 19,794,373.75
If the quotient is a whole number, then 4 and 19,794,373.75 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 | 79,177,495 | |
| -1 | 79,177,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 509 | 587 | 2,545 | 2,935 | 26,977 | 31,111 | 134,885 | 155,555 | 298,783 | 1,493,915 | 15,835,499 | 79,177,495 |
| -1 | -5 | -53 | -265 | -509 | -587 | -2,545 | -2,935 | -26,977 | -31,111 | -134,885 | -155,555 | -298,783 | -1,493,915 | -15,835,499 | -79,177,495 |
