If a two digit number has 6 divisors and the sum of the smallest 3 divisors is 10, then the number is

If a two digit number has 6 divisors and the sum of the smallest 3 divisors is 10, then the number is

6=2*3=(1+1)*(2+1)=5+1
So this two digit number is the product of the first power of a prime number and the second power of another prime number
Or the fifth power of a prime number, only 32 = 2 ^ 5, but the sum of the three smallest divisors is not 10
Now back to the first case. Since 1 is the smallest divisor, we focus on finding the other two divisors, and the sum is 9!
Now look at 9
9=2+7=3+6=4+5
If 2 + 7, we get 2 * 7 ^ 2 = 98
Why not 2 ^ 2 * 7? In this case, the third smallest divisor is not 7, but 4!
For 3 + 6 and 4 + 5, because they are not the smallest three divisors, because if 6 is the third smallest divisor, then 2 must be a divisor, so it is impossible for 6 to be the third smallest
Finally, the double-digit is 98
The divisor of 98 is
1,2,7,14,49,98, where 1 + 2 + 7 = 10, in line with!
