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 625,772,527, 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 | 625,772,527 | |
| -1 | -625,772,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 625,772,527.
Example:
1 x 625,772,527 = 625,772,527
and
-1 x -625,772,527 = 625,772,527
Notice both answers equal 625,772,527
With that explanation out of the way, let's continue. Next, we take the number 625,772,527 and divide it by 2:
625,772,527 ÷ 2 = 312,886,263.5
If the quotient is a whole number, then 2 and 312,886,263.5 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 | 625,772,527 | |
| -1 | -625,772,527 |
Now, we try dividing 625,772,527 by 3:
625,772,527 ÷ 3 = 208,590,842.3333
If the quotient is a whole number, then 3 and 208,590,842.3333 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 | 625,772,527 | |
| -1 | -625,772,527 |
Let's try dividing by 4:
625,772,527 ÷ 4 = 156,443,131.75
If the quotient is a whole number, then 4 and 156,443,131.75 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 | 625,772,527 | |
| -1 | 625,772,527 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 233 | 1,073 | 2,503 | 6,757 | 8,621 | 72,587 | 92,611 | 250,009 | 583,199 | 2,685,719 | 16,912,771 | 21,578,363 | 625,772,527 |
| -1 | -29 | -37 | -233 | -1,073 | -2,503 | -6,757 | -8,621 | -72,587 | -92,611 | -250,009 | -583,199 | -2,685,719 | -16,912,771 | -21,578,363 | -625,772,527 |
