The least common multiple of three different prime numbers is 154, which are (), (), ()

The least common multiple of three different prime numbers is 154, which are (), (), ()

The least common multiple is equal to the product of all their prime factors (if several prime factors are the same, compare which of the two numbers has more prime factors and multiply more times). That is, if there are repeated prime factors, take the group with the most, and multiply all the non repeated prime factors
154 can be decomposed into 14 * 11, 11 is a prime number, 14 is decomposed into 2 and 7, both are prime numbers, so the solution is 2,7,11
