The least frequent a number of (LCM) of two or extra numbers is the smallest optimistic integer that’s divisible by every of the numbers. For instance, the LCM of two and three is 6, since 6 is the smallest optimistic integer that’s divisible by each 2 and three. The LCM of two, 3, and 4 is 12, since 12 is the smallest optimistic integer that’s divisible by 2, 3, and 4.
The LCM is essential as a result of it may be used to seek out the least frequent denominator (LCD) of two or extra fractions. The LCD is the smallest optimistic integer that’s divisible by the denominators of all of the fractions. For instance, the LCD of the fractions 1/2 and 1/3 is 6, since 6 is the smallest optimistic integer that’s divisible by each 2 and three.
