Answer:

1. LCM OF 12, 15 & 21 = 420

2. LCM OF 17, 23 & 29 = 11339

3. LCM OF 8, 9 & 25 = 1800

Step-by-step explanation:

1. LCM OF 12 = 2×2×3

LCM OF 15 = 5

LCM OF 21 = 7

= LCM OF 12, 15 & 21 = 2²×3×5×7 = 420

2. LCM OF 17 = 17×1

LCM OF 23 = 23×1

LCM OF 29 = 29×1

LCM OF 17,23 & 29 = 17×23×29= 11339

3. LCM OF 8 = 2×2×2

LCM OF 9 = 3

LCM OF 25 = 5×5

LCM OF 8, 9 & 25 = 8×9×25= 1800
