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 2,494,975, 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 | 2,494,975 | |
| -1 | -2,494,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,494,975.
Example:
1 x 2,494,975 = 2,494,975
and
-1 x -2,494,975 = 2,494,975
Notice both answers equal 2,494,975
With that explanation out of the way, let's continue. Next, we take the number 2,494,975 and divide it by 2:
2,494,975 ÷ 2 = 1,247,487.5
If the quotient is a whole number, then 2 and 1,247,487.5 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 | 2,494,975 | |
| -1 | -2,494,975 |
Now, we try dividing 2,494,975 by 3:
2,494,975 ÷ 3 = 831,658.3333
If the quotient is a whole number, then 3 and 831,658.3333 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 | 2,494,975 | |
| -1 | -2,494,975 |
Let's try dividing by 4:
2,494,975 ÷ 4 = 623,743.75
If the quotient is a whole number, then 4 and 623,743.75 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 | 2,494,975 | |
| -1 | 2,494,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 53 | 175 | 265 | 269 | 371 | 1,325 | 1,345 | 1,855 | 1,883 | 6,725 | 9,275 | 9,415 | 14,257 | 47,075 | 71,285 | 99,799 | 356,425 | 498,995 | 2,494,975 |
| -1 | -5 | -7 | -25 | -35 | -53 | -175 | -265 | -269 | -371 | -1,325 | -1,345 | -1,855 | -1,883 | -6,725 | -9,275 | -9,415 | -14,257 | -47,075 | -71,285 | -99,799 | -356,425 | -498,995 | -2,494,975 |
