What is the smallest whole number, other than zero, that is a multiple of two or more given numbers?

The smallest whole number, other than zero, that is a multiple of two or more given numbers is known as the least common multiple (LCM). The LCM of a set of numbers is the smallest number that can be divided evenly by each of the numbers in that set. For example, to find the LCM of 4 and 6, you would look for the smallest number that both 4 and 6 can divide into without leaving a remainder. In this case, the LCM is 12, as it is the first number both 4 and 6 can divide into evenly.

The concept of LCM is especially useful in problems involving fractions, where you want to find a common denominator. It allows for effective addition or subtraction of fractions by providing a common base. Additionally, knowing how to determine the LCM involves prime factorization or listing out multiples, which reinforces the understanding of multiplication and divisibility.

The other terms listed do not relate to the requirements of the question. The greatest common factor refers to the largest number that can evenly divide all the given numbers, while a numerator is simply the top part of a fraction. A divisor is any number that can divide another without leaving a remainder, which does not specify a smallest
