2×3×5×7=210
The two smallest prime numbers are 2 and 3. So, the smallest number that is a product of two different primes that are squared is 22 x 32 = 36.
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
9 is the smallest natural number that is odd and composite: 9=3*3. 15 is the smallest natural number that is odd and a product of two numbers different from one and from each other: 15=3*5.
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
1150. because product of 3 x 5 x 7 x 11=1150, which is the least 4 digit number which can be expressed as product of primes.

1155, 3x5x7x11=1155.
The two smallest prime numbers are 2 and 3. So, the smallest number that is a product of two different primes that are squared is 22 x 32 = 36.
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
The two smallest prime numbers are 2 & 3. Their product is thus, 2 x 3 = 6.
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
36.
9 is the smallest natural number that is odd and composite: 9=3*3. 15 is the smallest natural number that is odd and a product of two numbers different from one and from each other: 15=3*5.
If the number is a product of two composite numbers, it must be 16, which is the product of 4 and 4. The prime factors of 16 are 2, 2, 2, and 2. The smallest composite number is 4, so the smallest possible product of two composite numbers is 4 x 4 = 16.

The first prime numbers are 2, 3, 5, 7, 11. When multiplied together the product is 2310. It is the smallest number that has the first five numbers as its factors.
