a. write the prime factorization of the least common multiple of A and B.

$A=2\cdot 3^2\cdot 5\cdot 7^3\cdot 11^3\cdot 13^2$

$B= 3^2 \cdot 5 \cdot 7^2 \cdot 11^2$

$\dfrac{2\cdot \cancel{3^2}\cdot \cancel{5\cdot 7^2} 7\cdot \cancel{11^2} 11\cdot 13^2}

{\cancel{3^2} \cdot 5 \cancel{\cdot 7^2} \cdot \cancel{11^2}}

=2\cdot 7\cdot 11\cdot 13^2=26026$

not sure if I went the right direction on this how do we get the prime factorization
