We will discuss here about the properties of l.c.m. (least common multiple).
1. The L.C.M. of two or more numbers cannot be less than any one of them. For example, the L.C.M. of 3, 8 and 12 is 24 which is not less than any given numbers.
2. If a number is the factor of another number, their L.C.M. is the greater number itself. For example, the L.C.M. of 8 and 16 is the greater number 16 itself.
