Question

Richie says that the least common multiple of a pair of prime numbers is the product of two numbers. Is he right or wrong? Explain why,

Answer 1

true
lcm = the lowest multiple of both numbers
to get this you would usually multiply all the prime numbers that the original number can be split into, since the chosen numbers are both primes (a number that is only divisible by itself) there is no need and the only thing we can do is multiply them together
