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 40,977,469, 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 | 40,977,469 | |
| -1 | -40,977,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,977,469.
Example:
1 x 40,977,469 = 40,977,469
and
-1 x -40,977,469 = 40,977,469
Notice both answers equal 40,977,469
With that explanation out of the way, let's continue. Next, we take the number 40,977,469 and divide it by 2:
40,977,469 ÷ 2 = 20,488,734.5
If the quotient is a whole number, then 2 and 20,488,734.5 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 | 40,977,469 | |
| -1 | -40,977,469 |
Now, we try dividing 40,977,469 by 3:
40,977,469 ÷ 3 = 13,659,156.3333
If the quotient is a whole number, then 3 and 13,659,156.3333 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 | 40,977,469 | |
| -1 | -40,977,469 |
Let's try dividing by 4:
40,977,469 ÷ 4 = 10,244,367.25
If the quotient is a whole number, then 4 and 10,244,367.25 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 | 40,977,469 | |
| -1 | 40,977,469 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 107 | 331 | 1,157 | 1,391 | 4,303 | 9,523 | 29,459 | 35,417 | 123,799 | 382,967 | 460,421 | 3,152,113 | 40,977,469 |
| -1 | -13 | -89 | -107 | -331 | -1,157 | -1,391 | -4,303 | -9,523 | -29,459 | -35,417 | -123,799 | -382,967 | -460,421 | -3,152,113 | -40,977,469 |
