Step-by-step explanation:

Approach 1. Integer numbers prime factorization:

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

273 = 3 × 7 × 13;

273 is not a prime, is a composite number;

390 = 2 × 3 × 5 × 13;

390 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

Calculate the least common multiple, lcm:

Multiply all the prime factors, by the largest exponents (if any).
