(iii) 10, 15
(iv) 14, 42
(v) 30, 40, 60
(vi) 15, 25, 75
Solution:
(i) 6, 9
Prime factorisation of 6 = 2 × 3
Prime factorisation of 9 = 3 × 3
Product of common factors = 3
Product of other factors = 2 × 3 = 6
LCM (6, 9) = 3 × 6 = 18

(ii) 8, 12
8 = 2 × 4 = 2 × 2 × 2
12 = 2 × 6 = 2 × 2 × 3
Product of common factors = 2 × 2 = 4
Product of other factors = 2 × 3 = 6
LCM = Product of common factors × Product of other factors = 4 × 6 = 24
LCM (8, 12) = 24.

10 = 2 × 5
15 = 3 × 5
Product of common factors = 5
Product of other factors = 2 × 3 = 6
LCM (10, 15) = Product of common factors × Product of other factors = 5 × 6 = 30

(iv) 14, 42
14 = 2 × 7
42 = 2 × 21 = 2 × 3 × 7
Product of common factors = 2 × 7
Product of other factors = 3

Product of highest powers of the common factors = 3 × 23 × 5 = 120
LCM (30, 40, 60) = 120

(vi) 15, 25, 75
15 = 5 × 3
25 = 5 × 5
75 = 5 × 5 × 3
Product of the highest powers of the common factors = 3 × 52 = 3 × 25 = 75
LCM (15, 25, 75) = 75

The traffic lights at three different road junctions change after every 40 seconds, 60 seconds and 72 seconds respectively. If they changed simultaneously together at 8 a.m at the junctions, at what time will they simultaneously change together again?
Solution:
This is an LCM related problem
Finding the LCM of 40, 60 and 72
60 seconds = 1 min
360 min = 6 min
Samacheer Kalvi 6th Maths Solutions Term 2 Chapter 1 Numbers Ex 1.2 Q7
LCM (40, 60, 72) = 2 × 2 × 3 × 5 × 2 × 3 = 360
After 360 seconds they will change again i.e after six minutes they will change again
i.e at 8.06 am they will change again simultaneously.

Question 8.
The LCM of two numbers is 210 and their HCF is 14. How many such pairs are possible?
Solution:
Let the numbers be 14x and 14y
14x × 14y = 14 × 210
⇒ \(x y=\frac{210}{14}=\frac{30}{2}=15\)
x = 1, y = 15; x = 3, y = 5
(14, 210), (42, 70) Two pairs

Question 9.
The LCM of two numbers is 6 times their HCF. If the HCF is 12 and one of the numbers is 36, then find the other number.
Solution:
HCF = 12
Product of two numbers = LCM × HCF
36 × other number = 72 × 12
Other number = \(\frac{72×12}{36}\)
Other number = 24

Question 14.
(i) Convert 480 days into years
(ii) Convert 38 months into years
Solution:
(i) Convert 480 days into years.
We know that 1 year = 365 days. [∵ 480 – 365 = 115 days ]
480 days = 1 year 115 days.
115 days = \(\frac{115}{30}\) months = 3 months 25 days
∴ 480 days = 1 year 3 months 25 days.
(ii) Convert 38 months into years
1 year has 12 months.
38 months = \(\frac{38}{12}\) years = 3 years 2 months
