Case Study Question 1:
A florist had 200 roses, 180 marigold and 320 orchids with him. He was asked to make garlands of flowers with only roses or only marigold or only orchids each containing the some number of flowers.
(i) The correct prime factorisation of 180 is:
(a) 2 x 2 x 3 x 3 x 5
(b) 4 x 3 x 3 x 5
(c) 2 x 2 x 9 x 5
(d) 4 x 9 x 5
Ans. Option (a) is correct.
Explanation: Option (a) has all the factors prime numbers. So it is the correct factorisation of 180.
(ii) The LCM of two coprime numbers is equal to
(a) 1
(b) the greatest number
(c) their product
(d) odd
Ans. Option (c) is correct.
Explanation: The LCM of two coprime numbers is their product.
(iii) What will be the largest number of flowers he can join together without leaving a single flower.
Sol. We should find the greatest number that is the HCF of 200,180 and 320.
200 = 2 × 2 × 2 × 5 × 5
180 = 2 × 2 × 3 × 3 × 5
320 = 2 × 2 × 2 × 2 × 2 × 2 × 5
HCF = 2 × 2 × 5 = 20
Hence largest number of flowers is 20.
(iv) Find the LCM of 200 and 180.
Sol.
LCM = 2 × 2 × 2 × 5 × 5 × 3 × 3 = 1800
