Answer 2

$a. \: 2 \: 15 \: 35 \\ 2 = 2 \\ 15 = 3 \times 5 \\ 35 = 5 \times 7 \\ cmmmc = 2 \times 3 \times 5 \times 7 = 210 \\ \\ b. \: 16 \: 20 \: 48 \\ 16 = {2}^{4} \\ 20 = {2}^{2} \times 5 \\ 48 = {2}^{4} \times 3 \\ cmmmc = {2}^{4} \times 3 \times 5 = 240 \\ \\ c. \: 6 \: 8 \: 14 \\ 6 = 2 \times 3 \\ 8 = {2}^{3} \\ 14 = 2 \times 7 \\ cmmmc = {2}^{3} \times 3 \times 7 = 168 \\ \\ d. \: 28 \: 49 \: 35 \\ 28 = {2}^{2} \times 7 \\ 49 = {7}^{2} \\ 35 = 5 \times 7 \\ cmmmc = {2}^{2} \times 5 \times {7}^{2} = 980 \\ \\ e. \: 25 \: 70 \: 100 \\ 25 = {5}^{2} \\ 70 = 2 \times 5 \times 7 \\ 100 = {2}^{2} \times {5}^{2} \\ cmmmc = {2}^{2} \times {5}^{2} \times {7}^{2} = 4900 \\ \\ f. \: 72 \: 54 \: 36 \\ 72 = {2}^{3} \times {3}^{2} \\ 54 = 2 \times {3}^{3} \\ 36 = {2}^{2} \times {3}^{2} \\ cmmmc = {2}^{3} \times {3}^{3} = 216 \\ \\ g. \: 8 \: 80 \: 120 \\ 8 = {2}^{3} \\ 80 = {2}^{4} \times 5 \\ 120 = {2}^{3} \times 3 \times 5 \\ cmmmc = {2}^{4} \times 3 \times 5 = 240 \\ \\ h. \: 120 \: 144 \: 240 \\ 120 = {2}^{3} \times 3 \times 5 \\ 144 = {2}^{4} \times {3}^{2} \\ 240 = {2}^{4} \times 3 \times 5 \\ cmmmc = {2}^{4} \times {3}^{2} \times 5 = 720$
