Answer 1

Answer:

(a) 9 and 4

9 =3 × 3

4 = 2 × 2

L.C.M of 9 and 4 = 2×2×3×3 = 36

(b) 12 and 5

12 = 2 x 2 x 3

5 = 5 x 1

L.C.M of 12 and 5 = 2×2×3×5 = 60

(c) 6 and 5

6 = 2 × 3

5 = 5× 1

L.C.M of 6 and 5 = 2 × 3 × 5 = 30

(d) 15 and 4

15 = 3× 5

4 = 2 × 2

L.C.M of 15 and 4 = 2 × 2 × 3 × 5 = 60

Yes, the L.C.M. is equal to the product of two numbers in each case. And L.C.M. is also the multiple of 3
