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 53,076,569, 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 | 53,076,569 | |
| -1 | -53,076,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,076,569.
Example:
1 x 53,076,569 = 53,076,569
and
-1 x -53,076,569 = 53,076,569
Notice both answers equal 53,076,569
With that explanation out of the way, let's continue. Next, we take the number 53,076,569 and divide it by 2:
53,076,569 ÷ 2 = 26,538,284.5
If the quotient is a whole number, then 2 and 26,538,284.5 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 | 53,076,569 | |
| -1 | -53,076,569 |
Now, we try dividing 53,076,569 by 3:
53,076,569 ÷ 3 = 17,692,189.6667
If the quotient is a whole number, then 3 and 17,692,189.6667 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 | 53,076,569 | |
| -1 | -53,076,569 |
Let's try dividing by 4:
53,076,569 ÷ 4 = 13,269,142.25
If the quotient is a whole number, then 4 and 13,269,142.25 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 | 53,076,569 | |
| -1 | 53,076,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 109 | 763 | 1,417 | 5,351 | 9,919 | 37,457 | 69,563 | 486,941 | 583,259 | 4,082,813 | 7,582,367 | 53,076,569 |
| -1 | -7 | -13 | -91 | -109 | -763 | -1,417 | -5,351 | -9,919 | -37,457 | -69,563 | -486,941 | -583,259 | -4,082,813 | -7,582,367 | -53,076,569 |
