What is the least common multiple of 14 28 and 98?

Answer 1

The least common multiple of 14, 28, and 98 is 196.

Express the numbers in their prime decomposition in power form and use the highest power of each prime across all the numbers:

14 = 2 x 7

28 = 2^2 x 7

98 = 2 x 7^2

LCM = 2^2 x 7^2

= 4 x 49

= 196

Answer 2

It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
