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 2,877,995, 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 | 2,877,995 | |
| -1 | -2,877,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,877,995.
Example:
1 x 2,877,995 = 2,877,995
and
-1 x -2,877,995 = 2,877,995
Notice both answers equal 2,877,995
With that explanation out of the way, let's continue. Next, we take the number 2,877,995 and divide it by 2:
2,877,995 ÷ 2 = 1,438,997.5
If the quotient is a whole number, then 2 and 1,438,997.5 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 | 2,877,995 | |
| -1 | -2,877,995 |
Now, we try dividing 2,877,995 by 3:
2,877,995 ÷ 3 = 959,331.6667
If the quotient is a whole number, then 3 and 959,331.6667 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 | 2,877,995 | |
| -1 | -2,877,995 |
Let's try dividing by 4:
2,877,995 ÷ 4 = 719,498.75
If the quotient is a whole number, then 4 and 719,498.75 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 | 2,877,995 | |
| -1 | 2,877,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 101 | 139 | 205 | 505 | 695 | 4,141 | 5,699 | 14,039 | 20,705 | 28,495 | 70,195 | 575,599 | 2,877,995 |
| -1 | -5 | -41 | -101 | -139 | -205 | -505 | -695 | -4,141 | -5,699 | -14,039 | -20,705 | -28,495 | -70,195 | -575,599 | -2,877,995 |
