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 37,745,461, 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 | 37,745,461 | |
| -1 | -37,745,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,745,461.
Example:
1 x 37,745,461 = 37,745,461
and
-1 x -37,745,461 = 37,745,461
Notice both answers equal 37,745,461
With that explanation out of the way, let's continue. Next, we take the number 37,745,461 and divide it by 2:
37,745,461 ÷ 2 = 18,872,730.5
If the quotient is a whole number, then 2 and 18,872,730.5 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 | 37,745,461 | |
| -1 | -37,745,461 |
Now, we try dividing 37,745,461 by 3:
37,745,461 ÷ 3 = 12,581,820.3333
If the quotient is a whole number, then 3 and 12,581,820.3333 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 | 37,745,461 | |
| -1 | -37,745,461 |
Let's try dividing by 4:
37,745,461 ÷ 4 = 9,436,365.25
If the quotient is a whole number, then 4 and 9,436,365.25 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 | 37,745,461 | |
| -1 | 37,745,461 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 41 | 299 | 533 | 943 | 3,079 | 12,259 | 40,027 | 70,817 | 126,239 | 920,621 | 1,641,107 | 2,903,497 | 37,745,461 |
| -1 | -13 | -23 | -41 | -299 | -533 | -943 | -3,079 | -12,259 | -40,027 | -70,817 | -126,239 | -920,621 | -1,641,107 | -2,903,497 | -37,745,461 |
