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 65,401,237, 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 | 65,401,237 | |
| -1 | -65,401,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,401,237.
Example:
1 x 65,401,237 = 65,401,237
and
-1 x -65,401,237 = 65,401,237
Notice both answers equal 65,401,237
With that explanation out of the way, let's continue. Next, we take the number 65,401,237 and divide it by 2:
65,401,237 ÷ 2 = 32,700,618.5
If the quotient is a whole number, then 2 and 32,700,618.5 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 | 65,401,237 | |
| -1 | -65,401,237 |
Now, we try dividing 65,401,237 by 3:
65,401,237 ÷ 3 = 21,800,412.3333
If the quotient is a whole number, then 3 and 21,800,412.3333 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 | 65,401,237 | |
| -1 | -65,401,237 |
Let's try dividing by 4:
65,401,237 ÷ 4 = 16,350,309.25
If the quotient is a whole number, then 4 and 16,350,309.25 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 | 65,401,237 | |
| -1 | 65,401,237 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 43 | 101 | 407 | 473 | 1,111 | 1,369 | 1,591 | 3,737 | 4,343 | 15,059 | 17,501 | 41,107 | 47,773 | 58,867 | 138,269 | 160,691 | 647,537 | 1,520,959 | 1,767,601 | 5,945,567 | 65,401,237 |
| -1 | -11 | -37 | -43 | -101 | -407 | -473 | -1,111 | -1,369 | -1,591 | -3,737 | -4,343 | -15,059 | -17,501 | -41,107 | -47,773 | -58,867 | -138,269 | -160,691 | -647,537 | -1,520,959 | -1,767,601 | -5,945,567 | -65,401,237 |
