Question

The LCM and HCF of two rational numbers are equal,then the numbers must be --------- a)prime b)co-prime c)composite d)equal please do with step by step explanation​

Answer 1

Answer:

L.C.M and H C.F are equal .

For ex: No. taking 10

H.C.F. of 10 = 10

L.C.M. of 10 = 10

L.c.m. and H.c.f. are considered to be a rational no. hence, they are equal.

H.c.f. and L.c.m. prime no.'s will not be equal to their H.c.f. or L.c.m.

In Co primes the value of H.c.f. will be 1 and that is not a possible answer.

Composite are the no.'s which are not prime no. and that will not be a right answer.

So, the answer'll be D) Equal.
