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 37,220,155, 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 | 37,220,155 | |
| -1 | -37,220,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,220,155.
Example:
1 x 37,220,155 = 37,220,155
and
-1 x -37,220,155 = 37,220,155
Notice both answers equal 37,220,155
With that explanation out of the way, let's continue. Next, we take the number 37,220,155 and divide it by 2:
37,220,155 ÷ 2 = 18,610,077.5
If the quotient is a whole number, then 2 and 18,610,077.5 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 | 37,220,155 | |
| -1 | -37,220,155 |
Now, we try dividing 37,220,155 by 3:
37,220,155 ÷ 3 = 12,406,718.3333
If the quotient is a whole number, then 3 and 12,406,718.3333 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 | 37,220,155 | |
| -1 | -37,220,155 |
Let's try dividing by 4:
37,220,155 ÷ 4 = 9,305,038.75
If the quotient is a whole number, then 4 and 9,305,038.75 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 | 37,220,155 | |
| -1 | 37,220,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 49 | 215 | 245 | 301 | 1,505 | 2,107 | 3,533 | 10,535 | 17,665 | 24,731 | 123,655 | 151,919 | 173,117 | 759,595 | 865,585 | 1,063,433 | 5,317,165 | 7,444,031 | 37,220,155 |
| -1 | -5 | -7 | -35 | -43 | -49 | -215 | -245 | -301 | -1,505 | -2,107 | -3,533 | -10,535 | -17,665 | -24,731 | -123,655 | -151,919 | -173,117 | -759,595 | -865,585 | -1,063,433 | -5,317,165 | -7,444,031 | -37,220,155 |
