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 1,377,215, 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 | 1,377,215 | |
| -1 | -1,377,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,377,215.
Example:
1 x 1,377,215 = 1,377,215
and
-1 x -1,377,215 = 1,377,215
Notice both answers equal 1,377,215
With that explanation out of the way, let's continue. Next, we take the number 1,377,215 and divide it by 2:
1,377,215 ÷ 2 = 688,607.5
If the quotient is a whole number, then 2 and 688,607.5 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 | 1,377,215 | |
| -1 | -1,377,215 |
Now, we try dividing 1,377,215 by 3:
1,377,215 ÷ 3 = 459,071.6667
If the quotient is a whole number, then 3 and 459,071.6667 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 | 1,377,215 | |
| -1 | -1,377,215 |
Let's try dividing by 4:
1,377,215 ÷ 4 = 344,303.75
If the quotient is a whole number, then 4 and 344,303.75 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 | 1,377,215 | |
| -1 | 1,377,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 109 | 133 | 361 | 545 | 665 | 763 | 1,805 | 2,071 | 2,527 | 3,815 | 10,355 | 12,635 | 14,497 | 39,349 | 72,485 | 196,745 | 275,443 | 1,377,215 |
| -1 | -5 | -7 | -19 | -35 | -95 | -109 | -133 | -361 | -545 | -665 | -763 | -1,805 | -2,071 | -2,527 | -3,815 | -10,355 | -12,635 | -14,497 | -39,349 | -72,485 | -196,745 | -275,443 | -1,377,215 |
