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 37,746,545, 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 | 37,746,545 | |
| -1 | -37,746,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,746,545.
Example:
1 x 37,746,545 = 37,746,545
and
-1 x -37,746,545 = 37,746,545
Notice both answers equal 37,746,545
With that explanation out of the way, let's continue. Next, we take the number 37,746,545 and divide it by 2:
37,746,545 ÷ 2 = 18,873,272.5
If the quotient is a whole number, then 2 and 18,873,272.5 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 | 37,746,545 | |
| -1 | -37,746,545 |
Now, we try dividing 37,746,545 by 3:
37,746,545 ÷ 3 = 12,582,181.6667
If the quotient is a whole number, then 3 and 12,582,181.6667 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 | 37,746,545 | |
| -1 | -37,746,545 |
Let's try dividing by 4:
37,746,545 ÷ 4 = 9,436,636.25
If the quotient is a whole number, then 4 and 9,436,636.25 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 | 37,746,545 | |
| -1 | 37,746,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 15,313 | 76,565 | 260,321 | 444,077 | 1,301,605 | 2,220,385 | 7,549,309 | 37,746,545 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -15,313 | -76,565 | -260,321 | -444,077 | -1,301,605 | -2,220,385 | -7,549,309 | -37,746,545 |
