Question

mcm ( 14, 28 ) =
mcm (12, 16 ) =
mcm ( 30, 70, 50) =
mcm (3, 4, 8 ) =

Answer 1

MCM (14 - 28 ) = 28
MCM(12 - 16) = 48
MCM(30 - 70 - 50)= 1050
MCM(3 - 4 - 8)= 24

Answer 2

mcm (14,28)
14 =  2×7
28 = 2³×7
mcm = 2²×7 = 28

mcm (12,16)
12 = 2²×3
16 = 2⁴
mcm = 2⁴×3 = 48

mcm (30, 70, 50)
30 = 2×3×5
70 = 2×5×7
50 = 2×5²
mcm = 2×3×5²×7 = 1.050

mcm ( 3, 4, 8)
3 = 3
4 = 2²
8 = 2³
mcm = 2³×3 = 24
