Incorrect. For each pair, identify the lowest common multiple of the coefficients and then the lowest common multiple of the variable terms. For example, in the pair $\displaystyle{6}{{x}}^{{2}}{y}\usepackage{cmbright}\Huge\$ and $\displaystyle{4}{{x}}^{{2}}{{y}}^{{3}}\usepackage{cmbright}\Huge\$ , what is the LCM of 6 and 4? What is the LCM of $\displaystyle{{x}}^{{2}}\usepackage{cmbright}\Huge\$ and $\displaystyle{{x}}^{{2}}\usepackage{cmbright}\Huge\$ ? What is the LCM of $\displaystyle{y}\usepackage{cmbright}\Huge\$ and $\displaystyle{{y}}^{{3}}\usepackage{cmbright}\Huge\$ ?
