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 62,774,387, 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 | 62,774,387 | |
| -1 | -62,774,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,774,387.
Example:
1 x 62,774,387 = 62,774,387
and
-1 x -62,774,387 = 62,774,387
Notice both answers equal 62,774,387
With that explanation out of the way, let's continue. Next, we take the number 62,774,387 and divide it by 2:
62,774,387 ÷ 2 = 31,387,193.5
If the quotient is a whole number, then 2 and 31,387,193.5 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 | 62,774,387 | |
| -1 | -62,774,387 |
Now, we try dividing 62,774,387 by 3:
62,774,387 ÷ 3 = 20,924,795.6667
If the quotient is a whole number, then 3 and 20,924,795.6667 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 | 62,774,387 | |
| -1 | -62,774,387 |
Let's try dividing by 4:
62,774,387 ÷ 4 = 15,693,596.75
If the quotient is a whole number, then 4 and 15,693,596.75 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 | 62,774,387 | |
| -1 | 62,774,387 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 479 | 593 | 6,227 | 7,709 | 8,143 | 10,081 | 105,859 | 131,053 | 284,047 | 3,692,611 | 4,828,799 | 62,774,387 |
| -1 | -13 | -17 | -221 | -479 | -593 | -6,227 | -7,709 | -8,143 | -10,081 | -105,859 | -131,053 | -284,047 | -3,692,611 | -4,828,799 | -62,774,387 |
