Best Answer

Express every number in terms of its prime factors.

16 = 2 x 2 x 2 x 2 = 24

100 = 2 x 2 x 5 x 5 = 22 x 52

The LCM is the product of the highest power of each prime factor.

The LCM of 16 and 100 is therefore 24 x 52 = 16 x 25 = 400

16x, but usually the term LCM is used for two or more numbers, and you only gave me one number.
