Find the L.C.M. of the following numbers in which one number is the factor of other: (a) and (b) and (c) and (d) and . What do you observe in the result obtained?
Step 1: (a) Find L.C.M.
Applying Prime Factorization method,
Thus, L.C.M of and
Step 2: (b) Find L.C.M.
Applying Prime Factorization method,
Thus, L.C.M of and
Step 3: (c) Find L.C.M.
Applying Prime Factorization method,
Thus, L.C.M of and
Step 4: (d) Find L.C.M.
Applying Prime Factorization method,
Thus, L.C.M of and
Hence, we can conclude that if one number is the factor of the other, then the L.C.M. of the two numbers will be equal to the greater number.
