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 37,376,545, 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 | 37,376,545 | |
| -1 | -37,376,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,376,545.
Example:
1 x 37,376,545 = 37,376,545
and
-1 x -37,376,545 = 37,376,545
Notice both answers equal 37,376,545
With that explanation out of the way, let's continue. Next, we take the number 37,376,545 and divide it by 2:
37,376,545 ÷ 2 = 18,688,272.5
If the quotient is a whole number, then 2 and 18,688,272.5 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 | 37,376,545 | |
| -1 | -37,376,545 |
Now, we try dividing 37,376,545 by 3:
37,376,545 ÷ 3 = 12,458,848.3333
If the quotient is a whole number, then 3 and 12,458,848.3333 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 | 37,376,545 | |
| -1 | -37,376,545 |
Let's try dividing by 4:
37,376,545 ÷ 4 = 9,344,136.25
If the quotient is a whole number, then 4 and 9,344,136.25 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 | 37,376,545 | |
| -1 | 37,376,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 293 | 823 | 1,465 | 4,115 | 9,083 | 25,513 | 45,415 | 127,565 | 241,139 | 1,205,695 | 7,475,309 | 37,376,545 |
| -1 | -5 | -31 | -155 | -293 | -823 | -1,465 | -4,115 | -9,083 | -25,513 | -45,415 | -127,565 | -241,139 | -1,205,695 | -7,475,309 | -37,376,545 |
