Answer 1

a) 24,36= 4   b)28,42=7  c)30,45=5

a)36,48,56= 6   b)30,45,70= 5    c)48,60,72=6

Answer 2

1. (24,36)=2³×3²=72
(28,42)=2²×3×7=84
(30,45)=2×3²×5

2.a)36=2²×3²
54=2×3³
48=2⁴×3
⇒cmmmc(36,54,48)=2⁴×3³=16×27=432

b)30=2×3×5
45=3²×5
75=3×5²
⇒cmmmc(30,45,75)=2×3²×5²=2×9×25=450

c)48=2⁴×3
60=2²×3×5
72=2³×3²×5
⇒cmmmc(48,60,72)=2⁴×3²×5=16×9×5=144×5=720
