Question

If HCF (a,b) = 12 and a × b = 1800, then LCM (a,b) is ?

Answer 1

Given:

• HCF of a and b is 12.
• Product of a × b is 1800

To Find:

• LCM of a and b

Solution:

As we Know that,

• LCM × HCF = Product of two no.

➞ LCM × 12 = a × b (1800)

➞ LCM = 1800/12

➞ LCM = 150

Verification:

➞ 150 × 12 = 1800

➞ 1800 = 1800

Hence, Verified.

• LCM of a and b is 150.

Answer 2

Answer:

HCF of (a,b) × LCM of (a,b) = a × b. 12 × LCM = 1800. therefore LCM of a and B = 1800/12. = 150.
