Question

if the HCF of two numbers *a* and *b* is 7 then what is the LCM of *a* and *b* ?
options:
(a) ab
(b) 7ab
(c) ab/7
(d) 2ab​

Answer 1

Answer:

7ab is the answer thank

Answer 2

Answer:

option (C)

$\frac{ab}{7}$

Step-by-step explanation:

because,

product of the two numbers=LCM×HCF of two given numbers

$a \times b = lcm \times hcf \: of \: a \: and \: b \\ a \times b = 7 \times lcm \\ \frac{a \times b}{7} = lcm$

therefore,

$lcm = \frac{ab}{7}$
