Question

Verify that LCM of 12,20 and 30 is a multiple of their HCf

Answer 1

Answer:

Yes, LCM is Multiple of Their HCF. ✔️

Step-by-step explanation:

The LCM of 12, 20 and 30 is.... 60✔️ 12 = 2×2×3

20 = 2×2×5

30 = 2×3×5

Now,

LCM = 2×2×3×5.

= 60✔️

Then,

12 = 2×2×3

20 = 2×2×5

30 = 2×3×5

HCF = 2 ✔️

(Because 2 is common in all three 12, 20 & 30 )

NOTE : LCM 60 is Multiple of HCF 2.

Therefore,

LCM of 12, 20, & 30 is a Multiple

of Their HCF. ✔️
