Answer 1

$\red{2400 \: = \: {2}^{5} \times {3}^{1} \times {5}^{2} }$

$\red{3200 \: = \: {2}^{7} \times {5}^{2} }$

$\red{4200 \: = \: {2}^{3} \times {3}^{1} \times {5}^{2} \times {7}^{1} }$

$\red{4800 \: = \: {2}^{6} \times {3}^{1} \times {5}^{2} }$

$\bold{ \red{LCM = {2}^{7} \times {3}^{1} \times {5}^{2} \times {7}^{1} }}$

The LCM is 67200
