There are only two prime numbers that are consecutive numbers, 2 and 3. Their product is 2 x 3 = 6. The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)
Since prime numbers are defined as positive integers, any product of prime numbers will be positive.
Only if the numbers are co-prime.
The Least Common Multiple (LCM) of two prime numbers is the product of the two prime numbers. This is because prime numbers only have themselves and 1 as factors, so their LCM is simply their product.
No, because 28 can only be calculated as a product in the following ways: 1 x 28 2 x 14 4 x 7 In the above cases, 28, 14 and 4 are all non-prime numbers, which means that 28 cannot be a product of 2 prime numbers alone.
Every composite number ... that is, one that is not a prime ... can be written as the product of two or more prime numbers. The primes themselves are the exceptions. A prime number is the product of only ' 1 ' and itself, and ' 1 ' is not considered a prime number.
Composite numbers can be written that way.
3 and 7 are prime numbers whose product is 21.
The LCM of a set of prime numbers is their product.
It only takes three. 2 x 3 x 5 = 30

225 cannot be factorised into the product of only 3 prime numbers.

60 is 2 x 2 x 3 x 5 so it cannot be written as the product of only two prime numbers.
