Solution
The correct option is
A
Zero
Let the numbers be
16
a
and
16
b
, where
a
and
b
are co-primes.
We know that LCM
×
HCF=Product of two numbers, therefore, we have,
16
a
×
16
b
=
(
16
×
146
)
⇒
256
a
b
=
16
×
146
⇒
a
b
=
16
×
146
256
⇒
a
b
=
9.125
The co-primes with product
9.125
does not exist.
Hence, the number of possible pairs are zero.
