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 62,890,597, 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 | 62,890,597 | |
| -1 | -62,890,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,890,597.
Example:
1 x 62,890,597 = 62,890,597
and
-1 x -62,890,597 = 62,890,597
Notice both answers equal 62,890,597
With that explanation out of the way, let's continue. Next, we take the number 62,890,597 and divide it by 2:
62,890,597 ÷ 2 = 31,445,298.5
If the quotient is a whole number, then 2 and 31,445,298.5 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 | 62,890,597 | |
| -1 | -62,890,597 |
Now, we try dividing 62,890,597 by 3:
62,890,597 ÷ 3 = 20,963,532.3333
If the quotient is a whole number, then 3 and 20,963,532.3333 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 | 62,890,597 | |
| -1 | -62,890,597 |
Let's try dividing by 4:
62,890,597 ÷ 4 = 15,722,649.25
If the quotient is a whole number, then 4 and 15,722,649.25 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 | 62,890,597 | |
| -1 | 62,890,597 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 41 | 77 | 121 | 287 | 451 | 847 | 1,811 | 3,157 | 4,961 | 12,677 | 19,921 | 34,727 | 74,251 | 139,447 | 219,131 | 519,757 | 816,761 | 1,533,917 | 5,717,327 | 8,984,371 | 62,890,597 |
| -1 | -7 | -11 | -41 | -77 | -121 | -287 | -451 | -847 | -1,811 | -3,157 | -4,961 | -12,677 | -19,921 | -34,727 | -74,251 | -139,447 | -219,131 | -519,757 | -816,761 | -1,533,917 | -5,717,327 | -8,984,371 | -62,890,597 |
