Question

1. find the LCM and HCF of (15,24)​

Answer 1

Answer:

Prime factorisation of 15 = 3 × 5

And,

Prime factorisation of 24 = 2 × 2 × 2 × 3

HCF of 15 and 24 = 1

And,

LCM of 15 and 24 = 2 × 2 × 2 × 3 ×3 × 5 = 360.

------------------------------------------------

One number = 15

And,

Other number = 24

Product of two numbers = 15 × 24 = 360

LCM of two numbers = 360

And,

HCF of two numbers = 1

Product of HCF and LCM = 1 × 360 = 360.

Hence,

One number × Other number = HCF × LCM..

Answer 2

Answer:

The lcm and hcf of the 15,24 as a per 15=1,3,5,15

24=1,2,3,4,6,8,12,24 the common number=1,3 the lcm=4 the hcf =8
