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 37,778,015, 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 | 37,778,015 | |
| -1 | -37,778,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,778,015.
Example:
1 x 37,778,015 = 37,778,015
and
-1 x -37,778,015 = 37,778,015
Notice both answers equal 37,778,015
With that explanation out of the way, let's continue. Next, we take the number 37,778,015 and divide it by 2:
37,778,015 ÷ 2 = 18,889,007.5
If the quotient is a whole number, then 2 and 18,889,007.5 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 | 37,778,015 | |
| -1 | -37,778,015 |
Now, we try dividing 37,778,015 by 3:
37,778,015 ÷ 3 = 12,592,671.6667
If the quotient is a whole number, then 3 and 12,592,671.6667 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 | 37,778,015 | |
| -1 | -37,778,015 |
Let's try dividing by 4:
37,778,015 ÷ 4 = 9,444,503.75
If the quotient is a whole number, then 4 and 9,444,503.75 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 | 37,778,015 | |
| -1 | 37,778,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 121 | 205 | 451 | 605 | 1,523 | 2,255 | 4,961 | 7,615 | 16,753 | 24,805 | 62,443 | 83,765 | 184,283 | 312,215 | 686,873 | 921,415 | 3,434,365 | 7,555,603 | 37,778,015 |
| -1 | -5 | -11 | -41 | -55 | -121 | -205 | -451 | -605 | -1,523 | -2,255 | -4,961 | -7,615 | -16,753 | -24,805 | -62,443 | -83,765 | -184,283 | -312,215 | -686,873 | -921,415 | -3,434,365 | -7,555,603 | -37,778,015 |
