Question

2. Three numbers are in
the ratio of 23.4 and
their LCM is also 240
Their H.CF​

Answer 1

Step-by-step explanation:

Dear Sakshi,

Let the numbers be 2x, 3x and 4x, LCM of 2x, 3x and 4x = 12x

=> 12x = 240

=> x = 240/12 = 20

H.C.F of 2x, 3x and 4x = x = 20 (Because x is the common factor)

Else if you put the value of x then numbers are 20,60 & 80 respectively and clearly the HCF of these three digits is 20.

Answer 2

Answer:

2×3×4=24

24= 240

10

numbers = 2×10 = 20

3× 10 = 30

4 × 10 = 40

HCF

20 = 5×2×2

30= 5× 3× 2

40 = 5×2×2×2

common factors = 5×2

therefore HCF = 10
