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 2,470,475, 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 | 2,470,475 | |
| -1 | -2,470,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,470,475.
Example:
1 x 2,470,475 = 2,470,475
and
-1 x -2,470,475 = 2,470,475
Notice both answers equal 2,470,475
With that explanation out of the way, let's continue. Next, we take the number 2,470,475 and divide it by 2:
2,470,475 ÷ 2 = 1,235,237.5
If the quotient is a whole number, then 2 and 1,235,237.5 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 | 2,470,475 | |
| -1 | -2,470,475 |
Now, we try dividing 2,470,475 by 3:
2,470,475 ÷ 3 = 823,491.6667
If the quotient is a whole number, then 3 and 823,491.6667 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 | 2,470,475 | |
| -1 | -2,470,475 |
Let's try dividing by 4:
2,470,475 ÷ 4 = 617,618.75
If the quotient is a whole number, then 4 and 617,618.75 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 | 2,470,475 | |
| -1 | 2,470,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 743 | 3,325 | 3,715 | 5,201 | 14,117 | 18,575 | 26,005 | 70,585 | 98,819 | 130,025 | 352,925 | 494,095 | 2,470,475 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -743 | -3,325 | -3,715 | -5,201 | -14,117 | -18,575 | -26,005 | -70,585 | -98,819 | -130,025 | -352,925 | -494,095 | -2,470,475 |
