Question

Mate clasa a VI a:
Cmmdc: (24,80); (270,405,162)
Cmmmc: (225,40); (32,48,60)

Answer 1

24 = 2^3 × 3

80 = 2^4 × 5

C.m.m.d.c.(24,80) = 2^3 = 8

270 = 2 × 3^3 × 5

405 = 3^4 × 5

162 = 2 × 3^4

C.m.m.d.c.(270,405,162) = 3^3 = 27

225 = 3^2 × 5^2

40 = 2^3 × 5

C.m.m.m.c.(225,40) = 2^3 × 3^2 × 5^2 = 8 × 9 × 25 = 1800

32 = 2^5

48 = 2^4 × 3

60 = 2^2 × 3 × 5

C.m.m.m.c.(32,48,60) = 2^5 × 3 × 5 = 32 × 15 = 480
