A. 4
B. 5
C. 6
D. 3

Answer 1

The number 5 cannot be the HCF of 1200.

Step-by-step explanation:

Given data:

The LCM of two numbers = 1200

To find:

The number which cannot be their H.C.F = ?

Let the two numbers = x and y

We know that:

LCM × H.C.F = xy

Now check the options:

The factor of 12 = 1, 2, 3 ,4, 6 and 12.

Clearly, 5 is not a factor of 12.

Hence the number 5 cannot be the H.C.F of 1200.
