What is the relationship between the common multiple of two numbers and their minimum common factor?

The common factor of two numbers is the factor of their greatest common factor. The common factor of two numbers is the factor of the greatest common factor, and the greatest common factor is their multiple. If a larger number is a multiple of a smaller number, their common factor is the smaller number.

Two numbers whose common factor is only 1 are called prime numbers. If both numbers are prime numbers, then their greatest common factor is only 1. If two numbers are prime numbers, then their least common multiple is their product. If the larger numbers are multiples of the smaller numbers, then the larger numbers are their least common multiples.

Mutual prime number: Two natural numbers whose common factor is only 1 are called mutual prime numbers.

Simple fraction: A fraction in which the numerator and denominator are prime numbers is called a simple fraction.

Methods of finding the greatest common factor: prime factor decomposition and short division.

Step 2: Multiply

The method of finding the least common multiple: decompose prime factor and short division, that is, use the greatest common factor × their unique factor. ?
