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 1,554,175, 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 | 1,554,175 | |
| -1 | -1,554,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,554,175.
Example:
1 x 1,554,175 = 1,554,175
and
-1 x -1,554,175 = 1,554,175
Notice both answers equal 1,554,175
With that explanation out of the way, let's continue. Next, we take the number 1,554,175 and divide it by 2:
1,554,175 ÷ 2 = 777,087.5
If the quotient is a whole number, then 2 and 777,087.5 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 | 1,554,175 | |
| -1 | -1,554,175 |
Now, we try dividing 1,554,175 by 3:
1,554,175 ÷ 3 = 518,058.3333
If the quotient is a whole number, then 3 and 518,058.3333 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 | 1,554,175 | |
| -1 | -1,554,175 |
Let's try dividing by 4:
1,554,175 ÷ 4 = 388,543.75
If the quotient is a whole number, then 4 and 388,543.75 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 | 1,554,175 | |
| -1 | 1,554,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 83 | 107 | 175 | 415 | 535 | 581 | 749 | 2,075 | 2,675 | 2,905 | 3,745 | 8,881 | 14,525 | 18,725 | 44,405 | 62,167 | 222,025 | 310,835 | 1,554,175 |
| -1 | -5 | -7 | -25 | -35 | -83 | -107 | -175 | -415 | -535 | -581 | -749 | -2,075 | -2,675 | -2,905 | -3,745 | -8,881 | -14,525 | -18,725 | -44,405 | -62,167 | -222,025 | -310,835 | -1,554,175 |
