Write natural numbers from 360 to 630 with odd divisors

If a is a divisor of natural number n, then Na is also a divisor of N. therefore, a and Na of N can be paired. Only when n = A2, a and Na will be equal. Therefore, when n is not a square number, its divisor is paired, so the number of divisors is even. When n is a square number A2, its divisor a can only be paired with itself, so the number of divisors of n is odd. There are 7 divisors between 360 and 630 So the divisors of 7 numbers are odd, they are 361400441484529576 and 625
