Lets find the least common multiple of 14, 28 and 98. This will be the smallar number which can be exactly divided by each of our numbers.
First, we need to find the prime factorization of our numbers, that is,
14=2 x 7
28= 2x2x7
98=2x7x7
Then, the LCM is
[tex]\begin{gathered} \text{LCM}(14,28,98)=2\times2\times7\times7 \\ \text{LCM}14,28,98)=196 \end{gathered}[/tex]then, the answer is 196
