Answer 2

Answer:

Q-1.

ans--

(a) 24 = 1 x 24 = 2 x 12 = 3 x 8 = 4 x 6 = 6 x 4

Factors of 24= 1,2,3,4,6,12,24

(b) 15=1 x 15 = 3 x 5 = 5 x 3

Factors of 15 = 1, 3, 5, 15

(c) 21=1 x 21 = 3 x 7 = 7 x 3

Factors of 21 = 1, 3, 7, 21

(d) 27= 1 x 27 = 3 x 9 = 9 x3

Factors of 27 = 1, 3, 9, 27

(e) 12 = 1 x 12 = 2 x 6 = 3 x 4 = 4 x 3

Factors of 12 = 1, 2, 3, 4, 6, 12

(f) 20=1 x 20 = 2 x 10 = 4 x 5 = 5 x 4

Factors of 20 = 1, 2, 4, 5, 10, 20

(g) 18=1 x 18 = 2 x 9 = 3 x

Factors of 18 = 1, 2, 3, 6, 9, 18

(h) 23=1 x 23

Factors of 23 = 1, 23

(i) 36== 1 x 36 = 2 x 18 = 3 x 12 = 4 x 9 = 6 x6

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Q2

ans

(a) 5 = 5 × 1= 5; 5 × 2 = 10; 5 × 3 = 15; 5 × 4 = 20;.

5 × 5 = 25. 5, 10, 15, 2, 25

(b) 8 = 8 × 1 = 8; 8 × 2 = 16; 8 × 3 = 24; 8 × 4 = 32;

8 × 5 =40. 8,16,24,32,40

(c) 9 = 9 × 1 = 9; 9 × 2 = 18; 9 × 3 = 27; 9 × 4 = 36;

9 × 5 = 45. 9,18,27,36,45
