1155, 3x5x7x11=1155.
The two smallest prime numbers are 2 & 3. Their product is thus, 2 x 3 = 6.

If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.
Smallest composite number dividable by prime numbers is product of them all. In this case it is: 2x3x5x7x11 = 2310.

2×3×5×7=210
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 least number that is the product of two different primes that are squared is 6. This is because 6 is the product of 2 (which is squared as 2^2) and 3 (which is squared as 3^2), both of which are prime numbers. Any smaller number would not be the product of two different primes that are squared.
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.
