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 2,421,475, 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 | 2,421,475 | |
| -1 | -2,421,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,421,475.
Example:
1 x 2,421,475 = 2,421,475
and
-1 x -2,421,475 = 2,421,475
Notice both answers equal 2,421,475
With that explanation out of the way, let's continue. Next, we take the number 2,421,475 and divide it by 2:
2,421,475 ÷ 2 = 1,210,737.5
If the quotient is a whole number, then 2 and 1,210,737.5 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 | 2,421,475 | |
| -1 | -2,421,475 |
Now, we try dividing 2,421,475 by 3:
2,421,475 ÷ 3 = 807,158.3333
If the quotient is a whole number, then 3 and 807,158.3333 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 | 2,421,475 | |
| -1 | -2,421,475 |
Let's try dividing by 4:
2,421,475 ÷ 4 = 605,368.75
If the quotient is a whole number, then 4 and 605,368.75 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 | 2,421,475 | |
| -1 | 2,421,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 101 | 137 | 175 | 505 | 685 | 707 | 959 | 2,525 | 3,425 | 3,535 | 4,795 | 13,837 | 17,675 | 23,975 | 69,185 | 96,859 | 345,925 | 484,295 | 2,421,475 |
| -1 | -5 | -7 | -25 | -35 | -101 | -137 | -175 | -505 | -685 | -707 | -959 | -2,525 | -3,425 | -3,535 | -4,795 | -13,837 | -17,675 | -23,975 | -69,185 | -96,859 | -345,925 | -484,295 | -2,421,475 |
