Question

180=2²×3²×5,1400=2³×5²×7 then Lcm (180,1400)=​

Answer 1

Step-by-step explanation:

$180 = {2}^{2} \times {3}^{2} \times 5 \\ 1400 = {2}^{3} \times {5}^{2} \times \times 7 \\ lcm(180.1400) = {2}^{3} \times {5}^{2} \times {3}^{2} \times 7 \\ = 8 \times 25 \times 9 \times 7 \\ = 56 \times 25 \times 9 \\ = 12600$

Answer 2

Step-by-step explanation:

180=2²×3²×5

1400=2³×5²×7

common factor= 2²×5=20

uncommon=2×3²×5×7=630

LCM=20×630

LCM=12600
